Ive been doing High Intensity Interval training recently the protocol as follows.... 2 min warm up/jog followed by a 15 sec all out sprint then 45 walk/slow jog...repeat this until i have reached 10-12 sprints then cool down for a couple minutes with a slow walk. This has really been working for me but i was wondering what everyone else does for their HIIT or high intensity cardio sessions?
