Hi!
I have a general question concerning stretch sessions. In a book about kettlebell training I read that it is very important to use a foam roller and do some myofascial massage prior to stretching. I'll try to translate the corresponding part: "Before you think about the length of your muscles and tendons, that is stretch, you should care about the quality of your muscle-, tendon- and fascia tissue. Otherwise the effect of stretching will be low. [...] We hardly can change a muscle's length, if we didn't change its density prior to that." (Sukopp, T. , 2016)
What do you think about that? Is it really that important to use the foam roller prior to stretching or is it just a nice "bonus"?
