This squat challenge is very good stuff.
Something magical* happened today (day seven). My ankles finally freed up enough so my weight is centred more evenly over my feet, and my hips and knees opened up so my hamstrings rest on calfs.
The squat is now actually a resting position – amazing. Although standing up again is tough going after five minutes down there!
*OK maybe not ‘magical’ but I was impressed anyway
