Get Firm, Toned Biceps and Triceps in Just Weeks

It was designed for both men and women to easily and conveniently tone, firm and strengthen the biceps and tricep muscles on both arms simultaneously. You control the intensity so can decide between bulking up versus toning.

The Flex Arms tones and strengthens the same muscles that are worked when you target your biceps and triceps lifting weights or doing other exercises like the elliptical machine, dips, pilates or yoga. It does all the work and you get all the benefits of stronger, more toned and firm biceps and triceps.

Just 30 mins a day

10 Customized Programs

100 Contractions per session


  • Pre-positioned gel pads are placed directly on your biceps and triceps.

  • Signals from The Flex Arms activate the nerves which control the biceps and triceps muscles.

  • Muscles contract and release giving you a deep effective workout.

You can use it whenever you want to- putting on your make up, making dinner, watching TV, folding laundry, helping the kids with their homework, taking a walk, surfing the net or even while you are at work... virtually anywhere and anytime.

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!

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. Thank you so much Flex Belt!!

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!

I have been using the Flex Belt for over 30 days now. 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(s). Also, I look forward to continuing the use of my Flex Belt and Flex Arms.

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

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.

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.
