This cardio is NOT for you.
You will need a treadmill and guts
Warm up incline of 8 speed 3.8-4 for 5 minute
Increase incline to 15 and do 15 min of sprints (30 on 30 sec recover)I had a speed of 5.5
Drop incline to 8 and do another 15 min of sprints (30 sec on 30 recover)my speed was 6.5
Slow down to your starting speed on this incline for 5 min of cool down
When I thought of this cardio it seemed fairly easy but half way through I could taste my heart beating!!! That's a good sign right?
