My friend recommended some GNC supplements to take before running and before strength training.
She likes this one before runs: www.gnc.com/product/index.jsp?productId=12
She takes this one before weights: www.gnc.com/product/index.jsp?productId=13
She also says she drinks a protein shake after working out for a protein boost and aid in recovery. That sounds like a lot of calories to me though!
I am concerned that all of these things are full of weirdo chemicals, may taste disgusting -- and they're also pretty expensive. On the other hand, she swears they give her more energy for runs and allow her to see faster results from strength training. What are your thoughts?
