Following a mild bollocking from Will, my sports injury guru, I've been working hard on strengthening the muscles around my knee.
80 one legged squats per day
40 one legged calf pushes per day
30 secs on body blade balanced on right knee per day (if I overbalance then I have to start again until I complete 30 secs)
Am feeling the benefits and determined to keep it up.
Keep on nagging me, Will.
