max headroom you seem to have the same concerns as me, i am a bodybuilder and do heavy lifting every other day, on the rest days i do heavy cardio, these glues/tapes that are touted by others as being great for sweat and activity arent holding up well for even two days and they are very expensive, i love the way the system makes me look but if im going to have to rebond every single day then it just isnt worth it, im looking for something that will hold up to four days, hopefully someone else who has overcome this problem will chime in
