I can't remember which thread, but somebody at some point mentioned that everything below 90 degrees in HLL is rest, which is why the L-V Leg Lifts are harder than full ROM. And it's true, it is harder. But does that mean HLL in the L-V category should be trained over full ROM. Same with, say, bicep curls, should they just be lowered to 90 degrees flexion and then back to top? And squats, etc. Sorry if I seem silly. Also, these either/or situations are silly, but I'm still curious so if only 1 range of motion could be selected for a specific exercise, should it be 90degree (more difficult) or full ROM?
