> Running hurts my knees
I've been following ATG (from Ben Patrick, the "knees over toes guy", google/youtube it) for about 2 years and it has made a tremendous difference to my knee ability; I have a torn meniscus and the routines he suggest have allowed me to regain full functionality.

Applying both leangains and HST, I've managed to lose 2.5 kg of fat while gaining 4.5 kg of lean tissue in three month. I was 38 years old at the time (2009).
For that I am very, very grateful to HN.
Regarding knees' pain, please look into HST's principles and literature. 15+ repetitions incorporated there heals ligaments' and muscles' microinjuries.
