You don’t need to spend hours of cardio each week running on a treadmill or around your local park. All you need to do is thirty minutes of slow or high intense cardio sessions 4-5 days a week if that’s the only exercise you do.
Sometimes I do cardio on the same days as weight training. Cardio for me, usually consists of HIIT (high intensity interval training).
My goals are probably different than your goals, but all I want to do is to look completely lean and muscular without looking huge.
