Only had enough time for 20 min. on my stairclimber but I raised the intensity and holy bejesus, talk about a great workout, this was a change I needed, high intesity rocked and I burned almost as many calories! WooooHoooo!!!!

I am a firm believer in HIIT over regular cardio, you burn more cals in the 20 min than in 45 min cardio and on top of that the calorie burn extends well after the workout as it does when weight lifting.
