So what they are trying to do is rid the body of water (liquid), which will translate in to less body weight. So how do they safely do this?
Let's get thing straight before they start, you can not lose three lbs of body fat in one hour, not unless you cut an appendage off & that is not an option. However, you can lose three lbs of overall body weight by losing water weight. Keep in mind Biology 101, the body could be consisted of 75% water, depending on the person's physical make up. The fatter the person the greater the difference in water weight than a muscular person, for example.
Therefore, if they eliminate as much salt from the body as feasible, the body's resistance to losing liquid decreases making it simpler to pass water weight through sweat.
The first matter they must address is our diet, & I am not speaking eating healthy, I am speaking eating sodium free. Salt, is the number reason a healthy person retains water. There's other health reasons which cause the retention of water, but those do not apply in our case.
There's probably plenty of different methods, some complex such as water pills which causes a person to continually urinate, to rid the body of liquid, but we'll use an elderly tried & true method. Sweating.
Sweat in the event you recall, is the body's natural function to icy itself when temperatures rise above normal. Therefore, they must generate heat to raise the body's temperature & force it to icy itself by sweating.
Be definite to wear a hat of some sort, preferably a winter sock hat, as the body gets rid of an wonderful amount of heat through the head. They don't need that to occur in this situation. They need to retain as much internal heat as feasible.
Dress yourself in warm clothing such as sweat shirts & sweat pants. You notice I use the plural type of shirts & pants because you will put on layers of these clothes, at least layers & if feasible.
After making a nice sweat, lay down & have someone wrap you in a blanket or wrestling mat. This will cause the body temperature to stay high after exercising, which will continue to extract liquid through sweat.
Exercise vigorously for at least ten minutes. This can be jogging, either in place or around the gym, leaping jacks, what ever you find comfortable, but which will work up a nice sweat.
As with any extreme or sudden body alter, there's dangers associated with this procedure. Never perform this procedure alone. Always have a coach or an wrestler with fast access to the coach, with you at all times. After making weight, re-hydrate with drinks such as Gatorade which are high in electrolytes.
After twenty minutes, unclothe & weigh in. You most likely have lost over pounds, but if not, you still have time to redress, with dry clothes, & repeat the procedure.
