Physio yesterday, she did some more work on my ankle and measured a few things, there was an improvement in my range already so she seems to have a good handle on whats going on.
She swapped out my bum raises TA activation exercise for a kneeling then arm raising one, it is much harder and somehow manages to flog my lower back, she said this is a good sign that my "inner" core strength is not great despite my posterior chain being strong enough.
I'm very surprised that not a single person commented on the DL video here or in the main thread given how quick everyone normally is to point out flaws lol
Gym tonight.
