Quite funny to read back on this now. Since this post I have joined a weightlifting club and am training three times a week. Therefore, for the last 3 months or so I have been doing lots of squats, shoulder presses, push presses, rows etc. Now I am starting to learn the clean and the snatch. At the moment, I can squat 95kg for a set of 5 (those are deep squats, till the back of the leg come together) and power clean 60 kg. The plan is to do 5 sets of 5 squats at 100 kg and get the power cleans up to 80 kg in a months time. I am still quite average at badminton since I only play once a week and don't really practice that much. I am, however, a lot stronger than I was before.
