What you're working: Quads, glutes, hamstrings and calves, while your core muscles keep you stable with correct form.
How to do it: Start out in a basic squat position, making sure your knees are not extending beyond your toes and with weight distributed evenly on your heels. Pivot to the right 90 degrees on left foot while maintaining the squat position. Pivot back to starting point, staying in squat position and then pivot to the left 90 degrees on right foot. Pivot back to starting point and come out of squat position. While standing up, do not lock your knees. This is one Jungle Squat; repeat for one minute.
Tip: Be sure to keep core engaged and back straight the whole time.
