Endurance

Cardio/fat burn – 20 minutes.

I like the elliptical machine, but you can use whatever you like. It should be low-impact and get your heart rate up to about 70% of your maximum. For me, that’s about 150 beats per minute. Bike, treadmill, jogging, whatever. Just make sure that whatever you’re doing doesn’t cause impact damage and that you don’t overdo it.

There are many advantages to doing your cardio first, primarily that it's a nice way to warm up your muscles and joints before the higher-impact weight and stretching sessions.
