After a warm-up, you will do 30 seconds at almost maximum endurance and then jog very slowly for 30 seconds before restarting the intervals for 12 repetitions.
You will finish the session with a 10 minute cool-down (not exceeding 65% of your HRMax) to relax your muscles and bring down your heart rate.
Your recovery will take place more quickly and your body will be more ready at the next session.
