Start slow!!! Try 10 minutes of rowing machine and 15 minutes of stationary bike. All that matters is that you elevate your heart rate to between 60-80% of your standing heart rate. Figure that out with this formula. 220-n[/]=heart rate...(n[/] is your age) multiply that by .6, .7, or .8 and that is your target heart rate. Later add another activity for ten minutes, or add 5 minutes to each current activity. Every other day is the right schedule for aerobic/cardio activity recovery time, whereas for anaerobic, it is 36-48 hour recovery time.
