The Hill Climb

Gradually increase your speed until you're at easy-run pace. Run for three minutes. Raise the incline to 2 percent for one minute, then to 4 for one minute. Lower the incline and rest for one minute. Raise to 4 percent and run for two minutes. Alternate running two minutes at an incline/jogging one minute on the flat for as long as you can.
