I haven't done anything for two weeks, we went to the theatre and it had really narrow rows - I managed to twist my knee when sitting down and then the constant up/down when people tried to squeeze past me and being frozen in a slightly hunchback position for 2.5 hours during the play really aggravated whatever I did, so even now my knee still hurts every now and then when I walk down the stairs. I'm hoping to get started this afternoon, just do the short routine and be careful not to bounce too hard!
