It's getting hot

Things are getting hot here in the desert. I'm mostly inside all day so I don't have to deal with the heat to much, but I still notice it. When I come home from work and walk into my house that has been shut up while I was gone, having to walk till it gets dark to do my run, coming home from my run with my clothes sticking to me, and doing my yoga with the fan blowing on me. As it gets warmer here I think I'm going to have a harder time making myself exercise. I am already seeing it happen. I don't want to eat my dinner to late, but with having to wait to take my run now I'm having problems. I have to know eat before my run, which sometime depending on what you have to eat you still fill very full while running and it makes me fill sick. Also I'm now trying to add the yoga in so I'm working on when to do that too.
