I have started to follow Thomas Kurz' method decribed in "Secrets of stretching", apart from dynamic stretching 'cause I always mess up pelvic alignment and end up with pain in the hips. If anybody has followed it, I have some questions. Kurz states that before starting leg exercises, I should be able to do this exercise 15reps x 3 holding a weight that is 1/3 of my body weight (approx 17 kg in my case). Now this is a problem for me because I have no access to weights, and using homemade stuff - formerly: my school bag full of books and similar creations - I can get maximum 10 kg. Do you think it could be enough or not? Also, in that exercise I tend to rely a lot on my legs' strength to hold onto the bench, which I shouldn't do since I have tendinitis in my shins and they hurt like hell doing that. I wouldn't want to interrupt the training as this problem has already messed up 3/4 of the training I had planned to do. Can I do this other exercise instead? Last but not least, do you know if there is a valid bodyweight exercise to the strength program suggested, or do I have to home-make some other weights?
