is it ok to lift weights the day before the game

I would avoid lifting the day before a game, especially as a pitcher. You should try to give the muscles 24-48 hours to heal and regain their strength.

Chucky,
Absolutely, unequivocally, undeniably NOT!

You need to figure this out for yourself. Your arm may feel fine but your body might be tired.

During the season you want to maintain. Its the offseason you build.

There's plenty on the web on this topic.

I would look around and try to find the most up to date (ie: current) opinions on this topic. There are many old wives tales out there about weights and baseball.

Good luck,

Someone who been there done that.

Save the weight training for immediately after the game or the following day.

You should have two solid days off weights before you pitch.

Other than that two days a week of proper weight training in-season goes a long way in performance and injury prevention. Notice I said Proper.
