Bodyweight Squats
Bodyweight squats use up to 4 muscles at the same time, including quads, hamstrings, glutes, and calves, and thus they are one of the quickest exercises to refresh weary leg muscles. They enhance blood flow, repair muscle fibres and raise joint ability without undue pressurising of your knees like heavy weights. The 2-3 sets a day will make your legs recover quicker and at the same time enhance your balance and posture.
