In the Body Weight Muscle Program there are some excersises that are too difficult for me for example the l sits and I don’t know any variations for those. Also the formatting is a bit confusing for example do we do all of these Pullups: 3 Sets to near-failure, Pullups (Easier Variation): 2 Sets to near-failure, Pullup Isometric Hold (any angle): 2 Holds until failure, or do we have to choose one?

Hey, Chrys here. One of the trainers at Hybrid.
For the L-sits, just regress it. Bend your knees, do tuck holds, or even keep one foot on the ground.
For the pull-up section, don’t do everything. It’s not meant to be all stacked together. Pick the level that matches you. If full pull-ups are too hard, do the easier variation. The isometric holds are optional add-ons if you want extra work. Lmk if this helps
