I've been working on camel spins since about August. So this is a fairly new thing for me and not something I spend tons of time on (what with MITF, jumps, other spins, and dance). However, in the last few weeks, my spinning knee has really started to bug me. As in, just beneath the kneecap feels, well, wonky. Like it might just give way. Somewhat painful. A couple of years of working on sit spins haven't had this effect.
Can anyone tell me what I'm doing wrong to cause the knee to feel this way? Or is this just ordinary post-40 aches and pains? I do cross train (weightlifting 3x/week, some cardio on a reclining stationary bike and the elliptical) so I don't think that overall strength is an issue, but it's possible that there's some isolated weakness somewhere.
