Stopped reading at stretching for muscle seperation. Stretching helps with flexibility and nothing else. They don't reduce DOMS, they have negligible effects on stretching the fascia and it does NOT seperate your muscles. Steroids and steroids only will cause noticeable muscle seperation. To think that stretching increases muscle recovery is a LIE. A brisk leisurely walk or shooting hoops on a rest day and dynamic stretching before working out will have a greater effect on strength and recovery than stretching
Edit:decided to read the article and of course it's about stretching the fascia. I am only going to say this once. There is NO reason to do stretching of the fascia (as described above) if you aren't doing steroids. All it's going to do is keep you out of the gym longer
