Barbell side split squat

Stand with your feet wider than shoulder-width apart, toes pointing slightly outward. Hold a barbell across your upper back, resting it on your traps. Engage your core and keep your chest up as you lower your body down into a squat position, bending at the knees and hips. As you lower, push your knees out to the sides and keep your weight on your heels. Lower until your thighs are parallel to the ground, then push through your heels to return to the starting position. Repeat for the desired number of repetitions.
