Sweat Suits are a Myth.

The only thing that you loose from using them is Water weight... and Electrolytes...

They are meant to make you sweat more by not letting heat escape from your body... this supposedly makes your body heat itself up to make the sweat evaporate? I've never head such rubbish in my life... How the hell does that work... even if they did make your use more calories up whilst training to the same level as not wearing one (I repeat: Rubbish) ... and by that I mean hitting as hard and often, for as long... doing as many reps etc why not do this:

Not wear the sweat suite and spend those calories on hitting harder... for longer... being more explosive and my constant?

There is no magic suit that allows you to train as hard as your normally do and use up more calories... if you put one of these suits on and trained as hard as you could you would burn exactly... ZERO calories more than if you didn't have one on... because you are exerting your self just as much either way.

And seeing as how all these suits do is make you sweat more... and seeing as how training is about A LOT more than just sweating... why make that the major 'thing' of your training?

I'd rather sweat naturally and perform to my best than sweat a lot and perform like shite.

Sweating isn't training... if you let your training suffer to sweat more than expect your results to suffer too.
