A new study published in the Journal of the International Society of Nutrition found that:
a moderate dose of caffeine may be sufficient for enhancing strength performance in resistance-trained women.
The women is the study were given 6 mg/kg of caffeine. Which for a 150lbs women is about 400mg of caffeine or 2 cups of coffee. When the women took the caffeine prior to working out they boosted their 1 rep max bench press by just under 2lbs. Not ground breaking strength gains but every little bit helps right? This fits in perfectly with my nutrient stacking concept and one more (small) reason to include some caffeine in your fat loss training program when you energy levels may be a little low.Caffeine enhances upper body strength in resistance-trained women [JISSN.org]
