Not gonna get involvded in a massive row here but!at the origin we do have steam pods and for some clients who have had trainsmart we do recomend a steam!
If for example they have a very low fat bump say 120 or below,they put there polar on sit in the booth then control the temp to get there bpm so its spot on.
Include some resistance and 30 mins fat burning then 30 mins in the steam pod it does seem to help.
And the end of the day the same as an ECA stack fat burning is raising your bodys core temp!
Our steam pods do increase the bpm quite dramatically!and of course raise your temp.
Not saying it works,but what a great end to a good workout
