Regressions for back and front squat
Many people have difficulty performing a back squat, or a front squat with good form. This can lead to more harm than good, so until you have good mobility and stability needed to perform your squats, you better regress your exercise to a level you can perform safely
This video shows the use of a sandbag instead of a barbell. This requires less thoracic and shoulder mobility, which are commonly lacking for people that have a faulty barbell squat.
In general when reviewing someone’s lift I try to find the main fault. I try to correct that with some coaching cues. If that does not work we need to do a mobility breakdown. After we have assessed the mobility we can try some corrective exercises and pick the right level of regression if needed.
