Love Cardio

Oh, you love cardio. I know it!!

If you plan on doing cardio on the same day as your resistance training, it's better to do it after your weight routine. While it's true that a 5-minute cardio warm-up is necessary before any resistance training, doing intense cardio beforehand will deplete most of your available blood sugar, which you need for those quick bursts of energy that resistance training requires.

Also, cardio will fatigue your muscles before you lift a single weight, which will prevent you from maxing out your muscles' potential. On the days when you are resting your muscles and doing cardio alone, the best time of day is absolutely any time. The most important thing is that you do it!
