In doing a Chad Waterbury program and I looked through each exercise. When it came to hanging leg raises I had a good idea of what it was, but not the full motion. I looked at a couple sites and they were almost all different. All of them had the same title but different movements. One suggested I push with my hips as high as i can go. Another even showed a guy put his legs up to the bar.
Im sure there are multiple ways to do this workout, but considering the first workout involves these:
Barbell Back Squat
Bent Over Row
Standing Barbell Curls
The hanging leg raises
Should I just do it where i lift my knees parallel to my waist?
