Cardio Workout 1: Elliptical Trainer

Start off with a five-minute warm-up, then do two minutes at 7-8 on a perceived exertion scale (10 being hardest, 1 being really easy), which will probably be 70%-80% of your maximum heart rate.

(to determine your max heart rate, subtract your age from 220.To determine your range , multiply that number by the percentage you're aiming for - in this case, 0.70 or 0.80. That total provides the number of heartbeats per minute your cardio training should produce.)
