Perhaps you don’t lack mobility.
Perhaps you aren’t weak.
Perhaps, there’s nothing wrong with you or how you move.
Perhaps, you haven’t trained, used, or practiced your mobility/strength/coordination like you did when you were younger.
Perhaps, you’ve out trained, used, or practiced other aspects of your physical ability than your mobility/strength/coordination as an adult.
Perhaps your body is adaptable and it has adapted to what you you’ve practiced over time.
Perhaps, give the practice, your body, and yourself, a bit more time. 🙂
Inspired by a conversation with a young adult about how his mother never worked out a day in the gym and has better ankle mobility in a deep atg squat. So much more to address, but for now, I think this is enough.
