I feel like the anger I have is justified, but that isn't helping the problem

I need a good way to release my anger in a positive way. Sometimes running helps but its way too hot and humid most days for that and I don't go to the gym. I might if I can find a gym here with a running track, I don't like treadmills. Any suggestions? Thanks
