Graded exposure and “keep using it so you dont lose it” are the keys to gaining and maintaining good functional movements required for comfortable competent daily living.
My aim is to be able to full depth squat (front squat with elbows straight ahead & overhead squat) at least 15kgs when I’m 90..more than 1/2 way there! So good so far)
Maintaining this requires ankle-knee-hip range, thoracic and shoulder mobility, lumbar stability. As Physiotherapists we are highly trained to help you keep your moving parts moving optimally.
