Hi All! I'm fairly new to this site and so I have seem to have so many questions to ask...I just recently started a weight lifting program four days a week. Legs for two and upper body for the other two. I also want to add running into my program perferrably three days a week. I'm new to running and I'm just curious what I should start out doing?? Minutes? Miles? I'm trying to go outside when the weather permits but I do have a treadmill if needed. Any suggestions on cardio to add to my workout?? My main goal is to tone up and stay lean but I also want the benefits only cardio can give you especially for helping to carve out the muscle I'm building. Thanx!
