If you want to burn more calories in your exercise session, interval training is the way to go.
What’s interval training? You shift rhythms.
For instance, instead of jogging for 30 min at a given pace, you sprint for 15 sec and then jog very relaxed for 45 sec.
You repeat this 10 times.
If you are biking, do the same, alternate sprints with recovery periods.
This will build up strength and burn on average twice as many calories as if you were just training on one steady pace.
