Assuming all else is equal, I wonder if it's a better idea to slightly elevate the heels and work on holding the foot-together-squat archetype for longer periods of time, or keeping the heels on the ground and using another technique to work on it.
I ask because I'm forever frustrated by my inability to get down to that position. I'm wondering how to scale and then progress. I can hit it easily barefoot when I just roll up a towel underneath my heels. But of course that's cheating and compensating for ankle mobility, which I should be (and am) working on. But would this tactic still help? Or is there a better way?
