We were talking about sweating legs today, and I'm just curious how you guys do it. At the race barn we always did sweats with a liniment mixture (I can't remember exactly what was in it). Rub the legs, cotton, saran wrap, and then standing wrap. Someone I was talking to today said they use furazone and DMSO, cotton, and wrap. NO saran as it would cause blistering. I have never heard of sweating without using saran, as I thought it was essential for actually creating the 'sweat'. Thoughts? Is it just because of that combination of ingredients is too strong? How do you guys sweat? Also, when/why, how long, etc?
