- backed by 20 years of real science and peer-reviewed publications.
"It sounds too good to be true," some of our customers used to say...
Until they put the BionicGym on their thighs, and eventually started sweating. "It's real exercise!" Why and how does it work?
Shivering is Nature's hack to burn calories. Muscles begin to shake in small movements, creating warmth by expending energy. Here's how BionicGym mimics that.
Impulses through the BionicGym Wraps stimulate the motor-neurons [nerves-to muscles] in the legs and glutei [bum], telling them to contract repeatedly. (They relax or lengthen by themselves). If enough muscle is actively contracting at optimal rates, they will shout out for blood to supply the oxygen and energy.
Your cardiovascular system [heart and blood vessels] works harder to deliver this blood, i.e., it trains.
Can you use it at 'easy' levels?
Yes, most people start using it at lower exercise intensity levels, and it still produces results. It's like exercising – you can either walk, jog, or run a marathon.
Here's what your BionicGym includes:
BionicGym is an App and a Wrap that delivers exercise by supercharging one of our body's natural processes: Shivering.
It uses Electrical Muscle Stimulation (EMS) to contract and relax the muscles of the legs at the optimal frequency, to delivery workout to your muscles as if they are on autopilot.
Set the intensity in the BionicGym app to lower intensities to burn extra calories while you multitask or at high intensities to raise your heart rate, work up a sweat and burn 500+ calories per hour.

Nancy Abell is using Bionicgym as part of her post partum weight loss journey, losing over 20 pounds.
Lasse Kronberg uses BionicGym to Supercharge his work and gaming sessions, losing over 33 pounds while he multitasks.
Tressa uses BionicGym while doing household chores, burning over 500 calories per hour!

BionicGym was created following 20+ years of testing and numerous peer-reviewed and published scientific studies.
Our studies have found multiple benefits to using BionicGym such as 500+ calories burned per hour, improvement in aerobic fitness, and a significant increase in heart rate and oxygen consumption, resulting in a cardio workout that is ultra-convenient and gentle on your joints.

With training: typically 500+ calories. In the laboratory when we’ve tested people - once they were used to BionicGym and had trained upon it - people were able to exercise at a rate burning 500+ calories/hr. Like the calories burnt on a bicycle, this figure varies enormously.
The BionicGym is designed to stimulate your leg muscles in way that mimics shivering. Crowe calls this "nature's way of burning calories without doing anything." A control unit placed inside a pair of leg wraps generates electrical impulses at a frequency of 7 to 8 Hz for optimal energy burn per muscle fiber. The impulses trigger continual muscle contractions, which then demand more oxygen and fuel to continue their effort. This increases your heart rate and, if you keep on going with the BionicGym, ultimately makes you breathless. And delivers a workout.
No. And because we are all so different it is difficult to give an accurate estimation without monitoring the effect on your body. Many people use a heart rate monitor as an estimate of calories burnt.
Yes! BionicGym at high intensities makes people sweat, be breathless and the heart races. For many people the heart rate responds immediately in the very first session. As they push up the intensity of the workout their heart rate increases like they were running. For others, it may take several weeks of training to acclimate. It depends upon your body type and fitness level. Some long distance athletes (with slow-twitch muscle fibers and big efficient hearts) may find that they need to train up these metabolic pathways with their BionicGym first to get a really good response. Likewise for some people who are unfit and lacking 'explosive' cardio-training. Here, we need to train up the muscle fibers to burn sugars at a high rate... then this places a high demand for oxygen and blood flow, increasing your heart rate.
The heart rate response is higher when you use your BionicGym standing and also depending on the Workout you choose - we recommend "Twinkle-Toes" standing as it brings in a lot of calf contractions.

I received a new product and started testing it. The BionicGym worked well without any problems. I gradually increased the intensity from the low stage to the high stage, but there was no problem with my body. While doing indoor exercise, I wore a wrap and gave an intermediate intensity of electrical stimulation. As a result, I haven't used it for a long time, but I sweated a lot and felt my body condition getting better. I think it is very effective to use BionicGym together when exercising. I will use it for another month and check how it works. First of all, I like Bionic Gym very much.

I have multiple sclerosis and I can’t say enough that everyone should own especially with a disability. I use mine daily and not only can I brag about smaller thighs but I feel stronger without MS fatigue. This has been worth every cent I paid. I feel great.

I’ve never been blown away enough to leave an unsolicited review for anything in my life. Just WOW. It works! No change in diet - just 1-2 hours a day and I’ve lost 30 lbs in 3 months. I love ❤️ BionicGym!
Nancy A. 5/5 Verified
I am so thankful, so grateful, for the Bionic Gym. I'm down 30 pounds of fat! This is weight I put on over 10 years ago with two pregnancies. I've tried meal replacement shakes and exercising at home with DVD's but I never got results. Bionic Gym has changed my life, and my family's life as a result. I'm continuing my journey with a goal to lose another 30 pounds and I know it's achievable now. And it's fun! I use it six days a week and look forward to it. I get an endorphin rush. Bionic Gym is truly the best investment I have ever made in myself. In addition to the weight loss, I've noticed other effects (46 yo female) I have no cellulite on my legs anymore. My menstrual cycle has improved tremendously. I have no junk food or sugar cravings. I don't look for junk at 3 PM like I have always done. It's available, but I'm not tempted by it at any time of the day. My overall mood has improved. My resting heart rate is so low, my nurse practitioner asked if I was taking medication to lower it. I can run a mile without being exhausted. You've changed my life. Thank you from the US!

I ordered and received mine in three weeks. It works fantastic. I'm even using it while write this. Is not a scam. It's a great product of an awesome quality. I'm absolutely happy about it. The thing is happy people doesn't review. If you're thinking about getting one, do it! I think it would be great for sooo many people. I give this product a 15 out of 10.

At first I was a bit skeptical if this will work but it takes a bit of adjustment at first to get comfortable with the device and the level. Honestly I was not happy at first but when I'm getting hang of it and use to it, it has become more and more effective gradually. Will continue to use and monitor the progress for now and I hope this will be my best investment for a healthier me and loose a few pound here and there.

3rd time use. I can barely tolerate 55 intensity over an hour! Im 35yo and work 12 hour night shift in the ICU with no more enthusiasm to workout after. But thanks to Bionicgym, after an hour, I was soaked with sweat and I slept good! Hopefully more benefits in the coming weeks!

5th workout, and with a bit of standing, and accentuating the BionicGym initiated movements and i got here... Overall the workout ended up looking like this...

I have a confession... I have not been able to motivate myself to exercise at ALL this whole quarantine. Between being full time mom, and part-time teacher/ therapist/ biller/ supervisor... and all the other things that go with running a small business, I just could not get up the motivation to do more in my free time than play video games or watch TV. So I did a thing. I got a Bionic Gym. Was able to buy a new one from a guy who had backed the campaign and bought two originally, so I got it for the Kickstarter price, but didn’t have to wait 2 years to receive it (thanks again, Adam!). Trying it out for the first time and I’ve been watching TV, putting around doing some chores, and wearing my crazy-pants. Heart rate has gotten up to 80-90bpm bc they say to take is easy and not overdo it much at first. My body has adjusted pretty well to increases in the intensity and I’m up to level 40. Feeling warm and clammy though not sweating too much yet. According to an online calculator, at my resting HR of 60, I’m burning about 12 calories an hour.... that’s not even a cookie! But at 80 BPM, I’m doing about 140 calories an hour, and I’m on hour three now of relaxing with this on. So that’s cool. More to come as we explore this experiment.

Just got mine 2 days ago. Jumped straight to twinkle toes. Held out for 2 hrs. Hope to keep up the progress.
Johnathan Y. 5/5
Started using it slowly and raising the intensity gradually because it takes our bodies a while to figure out what our tolerance to the pounding/flexing of the thigh muscles that we can handle. I am now able to maintain at 100.0 intensity for 1 hour the past several sessions. In return, I am perspiring like I have never done previously in my life. Even my forearms are sweating! Have never had this happen before. I look forward to a jailer healthy future with whatever it brings! Happy is as HAPPY does with my BionicGym as my helper! Thank you Dr. Louis Crowe & all the people trying to complete this wonderful project of love. I am sure there some tears along the way.

Bionic Gym has been easy and convenient to use, it feels a bit like having TENS or a massage on a lower setting so I don't mind wearing it. The lower settings feel nice and the stronger settings do feel like your legs are getting a work out. I have only had it week so its too soon to tell if it does burn calories and help with weightloss. Muscle stimulation has already been proven so I am looking forward to some good results to enhance my exercise program.

Just started using the Bionic Gym 2 weeks ago. Twinkle toes is my favorite so far. I was amazed how fast 2 hours goes by when you are at home and not at a gym.
Suzi S. 5/5 Verified
I don’t use it as consistently as I should, but there are times when I have used it consistently and noticed a few pounds fall off. It’s awesome because I can watch TV as much as I want and I’m not concerned with sitting around for hours because I know that with bionicgym, I’m still giving my muscle muscles a workout!!
