I'm doing HIIT 2-3 times a week and trying to maintain as much lean muscle as possible during my cutting cycle. Is it smart to leave out deads and squats if your using HIIT for cardio since it does make your legs sore and pumped during the sprinting intervals. I don't know if I could maintain a leg workout during the week doing that much HIIT cardio, but I will if the HIIT is going to cause me to loose strength and size.
