Hi, I am a 51 year old woman, I am over weight at 270 lbs. and I am only 5 2 , I have been on a weight loss, life change path for a little over a year and I have lost 95 lbs. I would like to know if I added Body Rush by Force Factor before my workouts, will it hurt me or make me gain weight. I understand that the product will help build muscle and give you the energy to workout longer.
