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.
