Well just wanted to let you guys in on these. Tried them for the first time today after watching the Squat Workout for about the 100th time last night. I used the purple bands for the main sets, did 4 x 6. These were tough. On the last rep of the last set I almost blacked out, I was only taking about 30 seconds rest between sets. And I realized that I was holding my breath on the sets. I also tried the greens at the end of my workout, these were even tougher. I still made my set of six. Next week will try the blues! One more thing, if you try these be sure to pause at the top for about a second and contract your glutes and hamstrings. This makes them BURN!
I also tried band GHR situps. These too were difficult as shit. Really made my hip flexors hurt.
Good training
