My calves are like rocks - they are far too tight but no amount of stretching or massage seems to do anything.
I should raise my desk more often. I tend to only do it for meetings and deliveries, but since I haven't had that many over the last few months, I have got lax.
Like rocks and sore, or just like rocks? :D
Toe separators
A 'roller'
Mat
Blocks
A few stances to hold
Balance board
These items have improved my lower body strength a lot and the stairs are much more comfortable than they were a year ago.
