im 5'9 220 and im trying to cut my weight to 180-200 but keep my muscle and ive heard HIIT training is a great way to lose the fat but keep the muscle. I've been doing a 15 minute training before lifting. I do 2 minutes of sprinting then a minute break of walking, then continue till i get to 15 minutes. I just wanted to know if this is the right time and the proper way to do it. Help is greately appreciated.
