I'm 48 year old woman, 5'6" 140 lbs. I'd like to loss 15 punds net of fat loss and muscle gain. I'm in okay shape and have started weight traing 3x weekly, dance 2x weekly and walk for one hour on the treadmill 4x weekly. I really want to tone up and loss fat. My measurements are 37-31-39. I can live with all of them except the waist measurement. My goal is to go from a 31'' waist to a 27" waist. Do you have any suggestions for my workout routine that we've had success with?
