I've heard you say, that squatting itself will improve flexibility. I suppose overall weightlifting, done with a proper ROM, will improve flexibility.
I was having a discussion with a karate instructor the other day. She was 100% convinced that weights were counterproductive to flexibility. She said that if I ever wanted to have extreme flexibility in my legs and kick high in the air and everything, I had to stop doing weights.
It didn't make sense to me. She said stuff like "strength training shorten your muscles" or "the more muscle mass you have, the more tension on your tendons", etc.
I told her that gymnastics and Jean Claude Van Damme and many others are very muscular and have a lot of flexibility. She told me that they didn't train with weights, that they have a different kind of training with a lot of stretching.
She also gave me some analogies on how it is harder to straighten 10 rubber bands together than 3 rubber bands.
Anyways, I am clueless on all this, because I don't really know how flexibility works and how it is related to muscle mass and hypertrophy. Care to enlighten me?
Is it possible to achieve a martial art/gymnastic flexibility by stretching everyday along with weightlifting?
I know this sounds kind of silly but she sounded very convinced.
