Hi, I'm fifty-eight years old and have spent most of my adult life at a desk. Consequently My mobility in my hips and ankles is poor. In particular, I can't squat to much below parallel. I can't get anywhere near a full ass-to-grass squat. So I'm wondering whether I have any business trying to master the Deck Squat at this stage.
Would it be better to spend a month or two (or however long it takes) getting a good ass-to-grass bodyweight squat, then progressing to working on my Deck Squat, rather than trying to master a Deck Squat right away with a body that is lacking in the fundamental flexibility required to achieve it?
