I have been a catcher (baseball) for 20 of my 26 years on this earth. So I have obviously developed a squat movement pattern of hamstrings on calves, and the weight on my toes with my heels high off the ground. (Pic included isn't me, but a good example of a catchers set up).
In this position I am easily able to keep a neutral spine and can obviously reach extreme depth. The problem is that this pattern has become so ingrained that it's how I feel most comfortable squatting in the weight room.
If I squat with heels elevated I am golden, no flexing of the spine and good depth. If I squat flat footed it all goes to hell. From what I understand this is mainly a calves issue? But how can that be since I spend a good 30+ hours a week in a catchers squat which is a constant stretch on my calves?
I squat (weight room) with a knee break instead of hip break so please no advice on sitting back or lower bar, as I am not looking to squat that way. Sorry for the long post, I am just confused as to why I can't reach depth without heels elevated even tho I feel I have exceptional flexibility.
Is it just a case of being a catcher for so long that the pattern has become natural?
