SL/PE 6

I slowed way down and taking my time and not rushing.  Re Arch ups:

do knees bend when at full extension (like doing a glute hamstring raise)?  Straight knee??  

Knees should not matter as your anchor should be at the hips on this one. Bending is ok if that is your setup  straight may be slightly more productive if you are anchored at the feet (like on a ghr machine).

Thank you
