After a warm-up (20 minutes of jogging and 3 progressive accelerations of 15 seconds), push yourself as far as possible for 4 minutes, then jog very slowly for 2 minutes before starting again. Complete 4 times.
Finish the session with a 10-minute warm-down (without exceeding 65% of your maximum heart rate) to relax the muscles and gradually lower the pulse.
You will recover more quickly and your body will cope with the following session better.
