I agree sometimes a fan will help or you can invest in a portable A/C (not window) they sell it cheap on Craiglist.

I do weight training on Day 3, Day 5. On Day 7 (usually on Thursday after work) i will take out the system, then wear a hat to the gym and i will do weight training and then follow by intense cardio. I usually will leave the system off overnight so my scalp can breathe. If i am not lazy in the morning before work, i will go to the gym for an hour with a hat on then come back, take a shower and put the system on. Most often not as i want to have more time putting the sytem before going to work, i dont want to rush it. The reason for removing on Thursday and wearing it back on Friday because i usually very active on the weekend and i like to look fresh on the weekend especially with the social gathering.
