At the end of my Glutes and Shoulder day I finished with this for my HIIT cardio. You want to feel a burn in your bum like no other then try it.
INCLINE 15% and the SPEED I chose was 4.0 mph. Just fast enough that I almost want to hold on to the tread but I CAN manage with NO HANDS cause it's only for 2 minutes. DEATH.
I went straight to the GHD machine, out of breath and busted out 15 hyperextensions. Squeezing your glutes the ENTIRE time. The burn from these two combined is unreal. I did this for 5 rounds. You got to get to the hyperextensions quickly following your walk.
