Sweating heavily during your workout isn't tied to fat burning.
When you join a gym with the goal of burning fat to build a slimmer body, it's easy to look for shortcuts -- especially because you might notice people taking shortcuts around you. An ineffective and dangerous shortcut is to cover your body in a sweatsuit, which is also known as a rubber suit or sauna suit, with the goal of increasing the amount you sweat during your workout. While you'll sweat more, you won't burn more fat wearing this garment.
Sweating Isn't Fat Loss
Wearing a suit that increases the amount that you sweat during your workout can easily trick you into thinking you've burned fat and lost weight. If you weigh yourself before and after your workout, for example, it's possible that you'll notice you've lost a pound during the workout. This apparent weight loss,
Suits Do More Harm Than Good
Although wearing a rubber suit doesn't do much for your appearance, the drawbacks to this exercise accessory are more than visual. When you wear the garment, your body temperature can increase to a point at which it negatively affects your health. Wearing a rubber suit elevates your risk of overheating and dehydration, while also potentially paving the way to kidney damage and even death. (See References 1 and 3)
Effective for Making Weight
In spite of their risks, many amateur and professional athletes use rubber suits to rapidly lose weight before competition. The use of these garments is notable in such sports as boxing, wrestling and martial arts, as athletes must meet specific weight criteria before competing. In these cases, athletes will wear a suit while exercising vigorously, but a trainer will monitor their progress. After lowering their weight to the correct amount, the fighter quickly hydrates to negate the lost water weight. (See References 2 and 4)
No Substitute for Hard Work
Instead of resorting to the use of potentially dangerous techniques as you attempt to burn fat, keep your workout healthy and just spend a little longer at the gym or on the road, depending on your desired exercise. Instead of wearing a rubber suit for a 30-minute treadmill run, for example, run on the treadmill a little quicker, a little longer or perform short intervals of moderate running and sprinting. Exercise several times a week and cut back on your calorie consumption to put your body in a fat-burning caloric deficit. (See References 5 and 6)
