Get the Range, then Add the Load! We are huge advocates of both @functionalmovementsystems for screening and @functional_range_conditioning for intervention based approach to improving movement potential. An important aspect question to ask if you don’t have ROM passively do you really have it actively? Not only that, do you control at large ROM during an integrated movement pattern? Not saying one screen is better than others but the Active Straight Leg Raise in the FMS is a pretty direct indication of ability to pull from a fixed height on the floor. How you change that ASLR comes down to creating capsular space, length on the progressive side (open angle) and contractile ability on the regressive side (closing angle). After that executing that pattern with less constraints or less direct support. Get the Range, Add the Load is not saying not training hard. It just prioritizes what to train hard with. Deadlifting from the ground or Bent Over Rowing is not as effective if I don’t have the prerequisite hip Flexion range and control.
