I didn't think it was physically possible to sweat that much!! Did the FitTV version of Low Max and was actually drenched, head to toe. Had the AC and a fan on, but it's 88 degrees at nearly 9 p.m. and there's only so much that one small air conditioner can do. I think it would kill me if I tried to do the actual entire DVD workout! How does anyone survive this thing, even in cooler temps? x( }(
