Is this safe to do? and plus I can't get the weight to the floor without bending my legs and I have to bend it more like a squat to keep my back straight and from rounding it due to bad hamstring flexibility. I would like to add this to my core exercise list.

I know I need to increase my core strength because it sucks. I cant even do 1 sit up without trying to jerk myself up and my feet come off the ground (cheating myself up). The only way I can get up is if I have something holding my feet and thats not good because hip flexors are involved. crunches did nothing to help. Now I am doing reverse crunches to get my flexion movement muscles stronger and then when I can get my butt off the ground without hanging onto anything and jerking myself up, then I should be able to do a sit up as well. Core strength is weak right now and I really need to work on these muscles a long with forearms. I cant forget to work lateral flexion either (side-side movements). I have been working on reverse crunches, rotation, and stability..but not side-side and an imbalance will create if I don't work on it and get it stronger just like hip dominant vs. quad dominant and vertical/horizontal push & pull. extension is automatically worked because of deadlifts and we all do hip extension work with our hip dominant exercises, so extension I say is my strongest.
