Starting position
Stand about shoulder width apart straight with your feet, the toes pointing forward. Relax your arms at your sides and hold a dumbbell in your hand.

Exercise technique
Bend your hips and knees, with your back on the floor. Keep your back straight throughout the movement and ensure that your knees do not go over the toes. Lower your body at an angle of 90 degrees (thighs should be parallel to the ground), and pause for a moment. Without moving your back, stretch your hips and knees to the starting position. Keep your weight back on your feet, not with your fingers. Repeat the movement for the desired number of repetitions. Repeat with the dumbbell in the other hand.

Top
Do not let your knees fall inward and never let them go on tiptoe. Keep to round your head up at all times and not the back. Client help your abdominal muscles, good posture.

Variation
Try one out on a limb this exercise.

Breathing
Breathe slowly and rhythmically through movement; not to hold your breath. Inhale as you lower your body and exhale to return to the starting position.
