2000mg/d calcium and 1000mg/d magnesium bro, should help a TON, make sure you drink atleast a quart of water during your time in the gym.

Also a good dose of a time released potassium would do a LOT of good and depending on how long you work out and what kinda diet your on a high glycemic carb drink migh also help.
