I do circuit training Mon-Fri to help with grip strength, muscle tone, etc. Also lighter weights, repetively, to strengthen deltoids, bicepts, etc. Have started barre pilates which helps flexability. At end of workout sit in sauna for about 15 minutes which I believe helps with heat tolerance. At matches when hot, drink at least one bottle of water per stage to prevent dehydration. If very hot also drink some type of electrolyte drink. Found that these procedures help shooting ability.
