Hi. Is it ok to mix a dynamic stretching ( just couple exercizes that uses leg muscles, it is something like a squats but with no weight) with max ot? When Ido those stretching exercises I feel a little musce burn during the exercise. I do 1 set 20 reps of each. So should I Avoid dynamic stretching after leg workout or is it ok?

MAXOT probably would not recommend it. Personally I wouldn't do it myself. I don't know that it will hurt you but I don't think it will help much either (not for muscle GROWTH anyway).
