Body Part: Thighs, Glutes, Calves
Step 1: Stand with feet straight and hip-to-shoulder-width apart and fingers interlaced behind your head. Draw in and brace the abs.
Step 2: Squat down to a maximum range you can maintain posture through, keeping knees in alignment with the toes. Keep chest out, eyes forward and elbows pressed out on the descent.
Step 3: Reverse the pattern and squeeze glutes pressing through heels to return to start position. Return the starting position. Maintain posture throughout.
Step 4: Repeat for the desired number of repetitions. Avoid knees collapsing inward, toes turning out, back slouching or overarching or chin jutting forward.
