Its easy to be a detractor; the challenge is to be a contributor. Using primarily osteophytic patterns, the investigators graded spine OA from 0 (normal) to 4 (very arthritic). Lifters with long femur lengths relative to shorter tibia (shin bone) lengths will naturally experience greater forward lean deeper into a squat compared to a lifter with proportional femur-to-tibia lengths [1, 3]. If a lifter is very tall, then sometimes it can be better to stick to block/pin pulls from the lowest height at which they can still keep proper alignment.
