Quoting Warpe be carefull not to overdo the exercise, or, like he said, you will need more sleep, and that could hurt your time at the tables. Just do this. Wake up, do 10-15 push ups. Brush your teeth, do 10-15 push ups. Take your shower, do 10-15 push ups. About a couple hours before you want to sleep, fire off a bunch of sit ups. Or jumpsnap. Just something that gets you going.
