In Intervals

If you have ever worked with a trainer, gone to an exercise class or a video you have probably heard that you want your heart rate up. But why and what is the easiest way to do just that? Intervals. Whether that be running, cycling, or cathletics, the point of your interval training should be to utilize both the aerobic and anaerobic energy sources of the body.

The aerobic, or with oxygen, is your rest period. This could be a slow jog, walking, a downhill, or ab work. The activity should bring your hear rate back round 50% of your max heart rate (220-your age).

The anaerobic, or without oxygen, is your burst of energy. This is the sprint part, the high knees, the hard uphill and isn't intended to last for an extended period of time. During the high intensity, energy is drawn from carbohydrates stored in the muscles as glycogen to be used while its by product, lactic acid, is the soreness you may feel the next day. Your heart rate should reach 85% of your max.
