This is possible. Squats mainly exercise the muscles in front and back of our thighs. When our knees bend, that is, when we squat, the muscles in the back of our thighs (hamstring muscles) will get more exercise, especially when our thighs squat below the water level, the muscles in the back of our thighs will contract more obviously, and when we get up, we will exercise the muscles in the front of our thighs, that is, quadriceps. Squat every day must be the standard, especially when squatting, the direction of the knee joint should be consistent with the direction of the toes. Don't buckle your knee when you get up, so as not to hurt your knee and straight back.
