Flex Arms - Stronger, More Toned Arms Now

The Flex Arms® is a product designed for both men and women that effectively and quickly tones up the Bicep and Tricep muscles utilizing cutting edge Electronic Muscle Stimulation technology. For a lot of people, the arms are a problem area that needs to be addressed. We have found that with this product it simply can produce results for everyone.

What we love about the Flex Arms® (and all the Flex® range of products, for that matter) is that they use FDA cleared medical-grade electronic toning technology that is clinically proven to work in just weeks for 100% of users! Using this state of the art Electronic Muscle Stimulation (EMS) technology, the Flex® products do the work for you. Sounds too good to be true? We thought so too, until we researched it even further. We are thoroughly impressed with this product – it is nothing short of exceptional….which is why it comes stamped with an FDA clearance.

The Flex Arms® tones and strengthens muscles and all you do is put the arms units on, select your intensity level (1-99) and it will literally flex your Bicep and Tricep muscles simultaneously for you. In fact – you can use it while watching TV, taking care of the kids, cleaning the house, working, taking a walk and more….talk about multitasking. Most of us complain about not having the time or motivation, but with modern day technology, there is no reason to miss your toning session now.

Medical Grade Technology
The interesting thing is that this ‘new technology’ isn’t really all that new. The Flex® range of products uses patented EMS (Electric Muscle Stimulation) technology, which is the same medical-grade technology that's been used for thirty years in the health care industry. This is the same technology used by physical therapists to exercise the muscles of their injured patients who can’t do it themselves. This is 100% medical science. In fact, The Flex® range of products are the first EMS products cleared by the FDA as class II medical devices for direct to consumer sales. You know the FDA doesn’t clear anything unless it is 100% thoroughly tested and proven to produce the results the product claims.

The parent company of the Flex® products is a medical device company headquartered in Galway, Ireland, with 40 years expertise designing, manufacturing and marketing EMS devices for medical and consumer use. Their EMS medical devices are used and prescribed in more than 5,000 clinics worldwide.

As you can see -- this is NOT a product that doesn’t produce results – it is a medical technology that works for everyone. It will work for you too. Just ask any of the over 2.5 million+ Flex® product customers worldwide…

All of the Flex® Products go through multiple clinical studies in order to achieve their FDA clearance. The Flex Arms® is no exception. It was tested in a very large clinical study with 300+ people, and the results were outstanding…

The Flex Arms® clinical study showed that in less than 8 weeks:

• 100% of users said it worked in some way
• 97% of users said they felt more confident in sleeveless shirts
• 96% said their arms were more attractive
• 92% of users said their arms were more toned
• 92% of users say it is easy to fit into their daily routine

Website In Focus
The Flex Arms® website is awesome. It is visually stunning, and all you need to do is check it out to understand how cool this product really is. There are diagrams that show how it flexes your muscles and videos that show how the technology works. This is a very real product, and their customers love it. The website also gives you information about the other Flex® products in their range. This is the same company that makes the famous Flex Belt®, which effectively tones and tightens your stomach. They also make a product just for women that tightens, tones and lifts your butt and thighs. Just imagine that as you get on with your busy day: you can simply wear the Flex Arms® while you work at the office or around the house, then wear the Flex Belt® while you walk the dog or help the kids with their homework, and then (if you are a lady) slip on the Flex Mini® while you make dinner for the family….and by the end of the day, you had a very good workout on your Arms, Stomach and (if a female) Butt and Thighs....the Flex® range is revolutionizing the world of achieving/maintaining a good figure!

The Flex Arms® on the official website costs $199.99. This is definitely extremely fair for this type of advanced medical-grade technology. The cool part is that all the Flex® products use the same power supply unit. So you can add onto your Flex Arms® order the other Flex® products (like the Flex Belt® & Flex Mini®) without their own power supply unit and get them for just $129.99 each. For instance, if you were to buy The Flex Belt® with its own controller, it would cost you the full $199.99.

Additionally -- All orders from the official website come with a very attractive 60-Day Money Back Guarantee. So if you don’t see the results on your arms, you just send it back and get your refund. It is a no-lose situation.

Final Thoughts
These products are the real deal. They literally go through about a year of clinical testing before each new piece to the range gets cleared by the FDA. This is not something new here – it is EMS technology, which, until the Flex® range was released, was only available in doctors’ offices. Now that the Flex® range has been granted ‘direct-to-consumer sales’ for EMS technology, the world of fitness and body-shaping is changing. They have already sold millions of pieces, and word of mouth is growing fast. If this product sounds interesting - just buy it and see what you think. If you aren’t happy – return it.

We highly recommend the Flex Arms® to anyone who wants attractive arms. For that matter, this whole clinically proven, FDA cleared range of products is perfect for anyone who would like to tone up (or maintain) their figure. Make sure and check the customer reviews here on our site….the customers say it all.

    Taking things to the next level, Thanks!

    As far as I’m concerned, the Flex Arms is a great complement to my workouts! It works my muscles to fatigue, and I am getting results a lot faster since adding this tool to my routine. I’ve been doing moderate weight workouts for years, and never got the look I’d envisioned am glad I can add this to my existing routing, but now, I am finally getting there!!!!!

    My biceps and triceps are feeling the burn

    Gotta say, this is an awesome product. Even though I do get to the gym pretty regularly, it’s always good to have something like this to help you push even harder. Not that I’ve ever seen anything quite like THIS before – I’d say the Flex Arms is in a class all of its own. I can FEEL it working every time, and man, does it burn in a good way! Of course, i’m the kind of guy who likes a challenge, you could set it to a lower level and not have it so intense. Definitely a good tool for my biceps and triceps, they feel more toned.

    Very impressive device!

    I’ve had the Flex arms for 4 weeks now and impressed – it really feels like a workout! I don’t have time to do much resistance training lately so this is the best thing i’ve found to keep my arms from getting flabby. Love it!

    With EMS technology you really feel your muscles contract = AMAZING!

    I have had a shoulder injury for now awhile which doesn’t all me to do a lot of arm exercises. So I got the flex Arms because i read really good things about it here and on other sites, i took advantage of the special price here and I really like the device. I have never tried EMS technology before and i can tell you it’s really powerful. You feel you muscles contact and you know it;s working, i also feel it at the end of each session, i have that burning sensation and my arms definitely feel firmer after a few weeks.

    30 days money back but my firmer arms are making me keep the flex arms!

    the flex Arms is sooo cool! I was super curious about it but really thought i was gonna have to send it back, i am skeptical but curious you know. They have a 30 day return policy on so i said what the heck right? I am so love with the results i am getting from using it everyday 5 days a week that there is no way i could send it back. Arms are firmer and def stronger because i notice that i am lifting more when i go to the gym. Great stuff.

    After 5 days....

    i have problems wanting to exercise my biceps on my own but my triceps it’s an other story so that’s why I got the Flex Arms, i read that it help with toning both biceps and triceps and after 12 weeks of using this magical device 5 days a week, i can tell you that it really does work. My triceps are way firmer adn that makes me happy. I plan using it once or twice a week now just to keep those awesome results i have gotten.

  9. 5 out of 5


    at first i was a little skeptical that the flex arms would do much for my arms, but after about 3 weeks, i have no doubt this works! i have been diligently following the instructions, using it for 5 days a week, for 20-30 min sessions a day, and although I could feel it working from day one, it wasn’t until after a couple weeks that I KNEW it was working. My arms are firmer and just yesterday, when i put on a sleeveless top, i could see they are more defined. SO awesome!

    Easy to use and great for multi-taskers

    Even after almost three months with Flex Arms, I can’t get over how simple it is to use! I put it on just about every day when I’m doing house chores, making dinner, or even reading. I am now the ultimate multi-tasker! I’ve had a set of dumbbells sitting in my closet for years that I haven’t touched – this is a great motivator for working the muscles.

    Understandably the "Staff pick"

    Well this was a “Staff Pick” product on and i thought it sounded good. I have always been embarrassed to wear tank tops and I just woke my first tank top in a very long time last night! The flex Arms has giving me confidence for sure, my arms are so much toner that even though, i stil need to work on them, I would say that they look a lot better, good enough for me to be proud to show them.

  12. 3 out of 5

    It helps but still need to lift...

    Unfortunately, my muscle tone just ain’t what it used to be. Seems like I gotta lift more weights, more often, to get the same kinds of results, though the Flex Arms is keeping it all on track and helping me progress faster. Great product, and love the deal I got from THANK YOU!

  13. 4 out of 5

    Woo Hoo!

    DId not really know what to expect, just thought the Flex Arms looked cool and I hate going to the gym. And i love shopping online! I can feel the contractions and try to go higher every day – I feel like I’m getting stronger, woo hoo!

  14. 5 out of 5

    Small yet super powerful!

    Awesome technology people!! Don’t be fooled by it’s tiny compact size, the flex Arms is super powerful. I am up to level 50 after 9 weeks of using it and are way toner already!

  15. 3 out of 5

    100% satisfied

    Found the system while searching the internet and was really impressed by the testimonies, the 100% satisfaction guarantee and especially that the product is backed by scientific data. My wife and I have been using Flex Belt and I alone have used Flex Arms for 9 months now. I must say even at our ages 74 & 72 we have noticed a difference in our appearance. I am a true believer in both products especially Flex Arms where I always had a problem. Now I can actually see definition like I have never seen. Thanks Flex Belt and Flex Arms.

  16. 5 out of 5

    Noticeable results after a month!

    After a month of using the Flex Belt my neighbors Mark and Tony asked me to order a set for them. They couldn’t believe my results. I look and feel so much better than I did before I ordered both the Flex Belt and Flex Arms. I can sit at work while it does it’s job and it takes no extra time away from my day. I wish I would have discovered these products a long time ago.

  17. 5 out of 5

    Using both the Flex belt and Flex Arms

    I purchased the Flex Belt and the Flex Arms 5 weeks ago. I have shoulder issues which prevents me from doing much of any kind of exercise on my arms so we thought this may be a nice alternative. My husband and I share them both just about every day…We have definitely noticed more definition in the triceps and biceps…Our arms are stronger. And as for the belt, the same thing. Definitely stronger abdominal muscles. We feel much stronger in our trunks. So we are in this for the long haul now, and we will start to see our newly sculpted muscles!! We will be ordering a second Flex Belt so that on those days where time is limited, we don’t have to share the belt and the power control.

    Works as good as it sounded on the video and reviews : I am pleased

    I WANT A FLEX BELT TOO… As I’ve gotten older, I find that traditional stuff I was doing before only gets me so far. When I saw Flex Arms, and read all about the EMS technology, medical grade device and all that, I was sold. I’m not usually prone to buying products like this, things I’ve seen promoted on TV or online but this one has all the solid backing behind it that I like to see. The studies, the testimonials, all that makes a difference. SO, I wasn’t at all surprised to feel and see results, just about from the very start. No, its not gonna melt away your fat or anything crazy, but it DOES tone muscle, and it does it quite well, imo.

    Best product I have found.

    Nothing to me is 5 stars, but this is very good. Let me tell you, this is the fastest arm toning I’ve ever done! I put on the Flex Arms, catch up on emails, bills, what have you, and the 30 minutes flies by! Best product I’ve found in a long time.

    biceps & triceps are looking good!

    I had great results with the flex belt for my abs so decided to try the same technology for my arms and boy I am pleased with the flex Arms. I am very think but had no definition whatsoever and always wanted sexy toned arms and after 10 weeks of using this almost everyday, I feel like i have super sexy arms, both my triceps and biceps feel and look toner! I eat really well and do tons of cardio, just needed some help toning and this awesome device did just that, just liek the flex belt helped with my abs. Thanks for the great deal on both.

    I recently ordered your products, and I feel great about The Flex Belt and the Flex Arms system. They are very good products that provide excellent results. I would highly recommend these products to all the people who want to look better and feel better about themselves. Thank you!

  22. 5 out of 5


    I have had my Flex Belt and Flex Arms for four weeks. I use them every day. I love both items, as they feel so good – like a massage after work. I have already seen a big difference in my stomach, and my arms are tighter. I am fifty three and couldn’t be more excited. It feels good to see a difference as the weeks pass. Will use them both forever. LOVE THEM BOTH!

    worth the money

    My wife got the Flex Arms for me and I must say at first i got mad at her for spending money on what i thought would not work but this is everything but that, it really works. It can even be challenging if you set the level on high. I started at a lower level but now that my arms are stronger, i am able to use it on a 60. My arms are toner and I am thinking about trying other flex products.

  24. 4 out of 5


    Normally I don’t get very excited about products, or take the time to write reviews about them. But, the Flex Arms is a different story. Every spring and summer, I tell myself I will FINALLY get the toned arms I’ve been wanting, and spend more time at the gym, more push ups and pull ups at home, and really strive to look good in sleeveless tops and dresses. By Sept. I’m usually somewhat satisfied, but also worn out. And then it gets cold, and I start covering up, and well, I get lazy. Then March comes and I am unhappy wiht my arms and the cycle starts all over again. Well, NOT THIS YEAR! THe plan is to begin the spring season with sexy toned arms, thanks to this awesome gadget, and they are looking mighty fine so far! I am FINALLY able to break the cycle.

  25. 5 out of 5

    'Staff pick' for a reason; & great savings too!

    I see that the Flex Belt is also a “staff pick” on, and after noticing how great the Flex Arms has been for my biceps and triceps, I’m anxious to get toned abs. Great to see $20 savings for that one as well.

  26. 5 out of 5


    I was desperate. My core had become weak. Doing basic house chores and yard work was becoming very uncomfortable. I ordered two Flex Belts, and one for arms, and one for butt lift. I was shocked at how my abdomen is finally lifting and looking a lot better. My appetite is decreasing and when I’m really tired I go watch my favorite show and work my abs, arms and butt. I totally feel better and just in 4 weeks time, I notice a huge difference in my abs, and also my energy. Thank you!

    Good when u r on the go

    I’m a real skeptic when it comes to fly by products. I just needed the slightest motivation to discover something. Then I tried Flex Belt. In just 3 weeks I already noticed a significant difference in my abdominal region, not to mention what Flex Arms has done for my biceps and my tri’s!! This product is it! I’m an electrician, and I co-own another contracting service. Point and case….. I’m always on the go, with very little time to spare!! This revolution is a dream maker and a life saver all in one!! I look, feel and think greater than I ever have before!!

  28. 5 out of 5

    Bringing sexy back!

    Seeing my friend’s awesome results is what made me want to try the flex Arms myself. It’s funny, i always took great care of my legs and abs but never really thought about my arms but now that I have toner arms, thanks to the flex Arms, i feel so sexy! The best part other than the fact that it toned my arms is that it is super easy and convenient to use. I wear them when i cook, clean or even surf on the web. I highly recommend this product if you need to tone your arms.

  29. 5 out of 5

    Getting stronger...

    After the first session, the Flex Arms made my arms so sore…in a good way! That’s how I know it’s working, and really stimulating my muscles. Feel like I’m gettin stronger every day.

    Wanna be like Bruce Lee

    Yeah I’ll give this 2 stars. I picked the flex Arms because first it sounds awesome and second it was FDA cleared. very important to me. Turns out i found out, EMS technology has been out for a very long time, even Bruce Lee is known to have used it for his training! Anyway, i am no Bruce Lee yet, but my arms are definitely toner than when i first started using the flex Arms 7 weeks ago, I can wait to be at the 12 weeks mark to see the final results. Good stuff.

  31. 5 out of 5

    feeling confident!

    My arms are looking GOOD! I’ve always been sort of embarassed to wear tank tops and strapless dresses, I feel like they usually just jiggle to much. I’m getting more confident every day since using the Flex Arms, and think I might even bare my arms at my daughter’s upcoming wedding! Can’t wait to wow my family and friends LOL this is truly a lovely product, and I am loving the results.

  32. 3 out of 5

    subtle, effective

    My arms do feel tighter and I think maybe stronger since first using Flex Arms about five or six weeks ago. I’ve always felt that it’s so hard to tone my triceps, in particular, and I hate how the used to look. I wouldn’t say it’s like, a huge transformation, at least not’s subtle but I do notice improvements and am excited to see what happens with continued use.

  33. 5 out of 5

    EMS Rules! I am so very pleased with my purchase.

    I have used The Flex Belt for a total of 45 sessions and my abs have changed like night and day! I also ordered the Flex Arms and it is AWESOME! Combining these two products with my daily workout regime is amazing! I was interested in EMS technology and did some research leading me to purchase the Flex Belt. It feels really intense when using the belt. Thanks so much!

    Flat abs, toned arms

    I’m 28 and have worked out on a regular basis about 5 days a week for the majority of my adult life. I couldn’t seem to get the definition I wanted from my workouts and specific abdominal workouts at that. I did a lot of research on abdominal devices and read a lot of testimonials and the Flex Belt was the one that I felt would be the best fit for me. Plus it had the money back guarantee – if I didn’t like it or it didn’t work. I was sold! I used it right away after I received it in the mail. It feels like a really great deep abdominal flex when I’m using it, doesn’t hurt or feel crazy uncomfortable. I followed the usage instructions and it is really paying off. I am very happy with the Flex Belt results. Being so happy with the Flex Belt purchase, I bought the Flex Arms System. Same as the Flex Belt – changed my life, and gave me the definition I had been sweating like crazy to achieve! I would highly recommend the Flex Belt products to anyone who is looking for the edge that will get them the desired results they’ve been working towards.

  35. 4 out of 5

    After 4 weeks...

    I have used the arm belt and ab belt for 4 weeks now. It feels like muscles are really working out and still even working after the belt is removed. I plan to continue using the belt and hope to see what results I can achieve by Christmas!

  36. 5 out of 5

    Getting ready for my wedding!

    My wedding is coming up and I will be wearing a strapless dress so I must have perfly toned arms for the big day! SO far, it’s been 5 weeks since I started using the flex Arms and i don’t regret buying it one bit. If anything i recommended it to all my bridesmaids. My arms are already toner and feeling tighter already. I am gonna look so good, i can’t wait!

  37. 5 out of 5

    medical grade, great price

    Before seeing and learning about Flex Arms I was familiar with EMS technology though never considered it for gaining bulk. Always thought of it as a rehab thing, in chiropractor or PT offices. Nice to see the medical grade technology available for home use, and at such a great price. Using this seems to aid in recovery, so on days I don’t get to the gym, I can still stimulate them to a lesser degree, or if I miss a workout day, go more intense. This provides a lot of flexibility and is really a genius product. I have no doubt my arms are firmer and stronger because of this, and I’m glad I found the discount on

    Goodbye, flabby arms!

    AGING IS NO FUN! Seems like everything starts to sag. My arms are what people see the most, so that was the first issue I wanted to tackle; I can’t go around in sweaters all summer! With the Flex Arms, I feel like I will have no more self-consciousness there this year! So next up, I want that Flex Mini I saw on here too and hope to have a lifted, toner butt as well!

  39. 5 out of 5


    D*mn it feels good to have toned arms!!! Thanks for featuring the flex Arms and for the savings!

    Works FAST, even for an older women!

    I saw an info commercial on the Flex Belt and Flex Arms. I have noticed no matter how much exercise I do, being over 50 and a woman, my body just didn’t seem to stay as firm as it once did. I thought about the product on and off for about six months. Finally I thought, I’d give it a try. I was pretty sure it wouldn’t work, and it was a stretch to order. I bit the bullet and bought both the Flex Belt and the Flex Arms. I started to show results within two weeks, much to my shock…I have raved about this product to friends, something I never do. I love these products, hope they last a long time and will buy a new one whenever I have worn these out! Thanks for such a great invention.

    amazing products

    I have been using the Flex Belt for over 30 days. I purchased The Flex Belt and Flex Arms so I could better define those specific muscles. Both are amazing and make you look and feel great. I recommend these products for anyone looking for the same effect. Also, I look forward to continuing the use of my Flex Belt and Flex Arms.

  42. 5 out of 5


    I love the Flex belt! It actually works and makes you feel that you had an AB workout! I can’t wait to come home from work to put it on. I just ordered the arm belts too. The BEST INVESTMENT I ever made. Thank you.

  43. 5 out of 5

    Don't forget: YOU control how hard/easy it is!

    it’s funny, my very, very first impression of the flex arms, when putting it on and powering up, was confused disappointment. i couldn’t feel a thing! then i realized i had control over the intensity, and started pushing the arrow up button. at around 15 i started to feel the contractions, and went up to 30 before deciding that was a good starting point. i guess i should’ve read the instructions first, i was just so excited to get started with it! i think it’s a good thing that we, as consumers, have control over the intensity of the workouts, and I for one am very pleased with this.

    Great for aging arms

    I had some sagging skin due to I guess aging under my arms and the flex Arms really helped tone this area for me. What an amazing technology. I got a free year subscription to Women’s health magazine too here with my order. A great deal!
