I find that:

(1) working out with weights or otherwise getting regular serious exercise leaves me feeling overall healthier, stronger, and more alert than when I don't, over time.

(2) After a heavy workout I have low energy and rather sleepy. If I work out first thing in the morning, I have a lower-energy day than if I work out in the evening.

(3) Working out is an absolutely fantastic way of purging the feelings of stress and (if I've had a bad session) tilt from my body.

I can't stress the third point enough. Intense exercise flushes out the physiological residues of stress and fight-or-flight excitement. For me, it leaves me much more balanced and relaxed after a tough session than otherwise.

If you are playing on a regular schedule, you might find it useful to schedule a regular workout after every session. It helps to be a member of a 24x7 gym, like 24 Hour Fitness. Or, you can keep a weight bench at home. The latter would work well for online pros.
