Grab the loaded barbell with your palms facing up (toward the ceiling). Your grip should be slightly wider than your shoulder width. Bend your knees and get ready for the initial lift. This is your starting position.
Lift the barbell and keep your back straight and head looking into the horizon as you bring the bar into your mid-section area. Keep your elbows tucked in. When lifting, the bar should come all the way up until it touches your shirt. Then, release the barbell back down to the original start position but don't extend your arms completely. You should always keep tension in your arms for optimal movement efficiency.
Finally, repeat entire movement for the desired or prescribed number of repetitions.
