This week as I can not get to the gym on Thursday I did the body pump class on Tuesday. Had a good session and used 4kg of weights for most tracks with 5 kg for the chest track and just 2 kg for the upright rows and upright raise track. My left knee is still not OK and my left quad gets very tight. This makes lunges very difficult, but I do them a little. I find that my left shoulder gets quite tight and painful when doing the chest track (second one) presumably it tightens up during the first warming up, all inclusive, exercise.
