Hello,I am beginner in MMA , and I have started learning double leg knee takedowns 1 week ago, and I think it is going fine for me, i don't lose momentum and can lift my opponent easily.But the question is, are my knees supposed to hurt? I mean it is not just skin pain from contacting the floor, it is inside. And when I squat doing some housework or something, they hurt the most. So will they adapt ,or am I killing my knees? Also, on the trainings we use the red and blue Eva mats, puzzle shape, and I also do the takedowns on a playground with rubber floor.
