Supplements for running and maintaining muscle mass
I currently am running to decrease my overall BF% but I am continuing to lift weights so that i do not look like a stick. I run 4 times a week at a good pace for 30-40 minutes and on off-running days i do my usual weightlifting. Dropping weight will inevitably deplete my muscle but i want to lessen the impact with the proper supplements (only natural). I am currently taking glutamine and i am well aware of its positive attributes. I would like to find out what other supplements are out there (again, natural only) that will aid in my goal of dropping my BF% and maintain my muscle.
