To get the most out of your interval training try the following:
- Add Resistance. Between sets of cardio do a set with dumbbells, resistance bands or with your body weight.
- Increase Speed. Really push yourself during the sprinting intervals. Remember, it’s only a handful of seconds.
- Lengthen Intervals. Add a few seconds to your intense intervals.
- Change Exercises. If you’ve been sprinting then switch to burpees or high knees.
