Grab parallel bars; hold your body at arm’s length (arms locked) above the bars. Your torso should be straight and leaning forward with your knees bent.
Lower yourself by flexing elbows; keep your elbows pointing backwards. Your shoulders and wrists are in the same line throughout the motion. Keep your torso straight and aligned with your thighs all the way through. Use your triceps (eccentric contraction) to bring your body back up. Breathe in as you go down and breathe out as you go up.
Make sure your hands are in the correct position and avoid extensive dorsal flexion in your wrists. As you go down, avoid lifting your shoulders and eliminate using your upper trapezius muscles. Keep your elbows close to your torso and pointing backwards; avoid sideway motion. Keep your torso straight and aligned with your thighs. Focus on abdominal breathing!
It is advised to use a spotter to hold your legs near your feet.
