All good points, and I'll incorporate them. Perhaps my full-on flash with the camera did me a bit of dis-service! As for lower body training, it is my wish that I can start doing this, but right now, I'm finding it almost impossible.
Re leg training - I'm in the UK, so it takes me 6 months to see a doctor, and if he can't see what's wrong with my leg, I wait 6 more months to see him again etc. For two years, they haven't been able to diagnose me, but gave me a diagnosis a few weeks ago, after horrendous daily pain.
Left knee: Hoffa's fat pad disease + fibular cartlige and cartlidge on the medial side of the knee. Also, damaged ankle ligaments.
Right knee: Tendinopathy - just can't seem to beat it. I've paid a ton of money to private physios etc to sort the problem out and their advice is always the same - here's an A4 sheet of exercises to do, you'll feel like gold in 6 weeks.
Two years later, nothing. I'm working hard on trying to correct this since I'm missing out on a shit load of sprinting sports which used to be my forte.
