I swear, it must have about 100 degrees inside my school. There isn't any air conditioning and to be honest, I love it. Most gyms these says really baby their members and it's hard to work up a good sweat and stay loose with the airconditioning blasting. In any event, I'm still learning a lot of the basics in Brazilian Jui Jitsu which has been enlightening coming from a Tae Kwon Do and Kajukenbo. There was virtually no ground defense or offense with those styles so I'm like a fish out of water still. Either way, I love the challenge.
