Remember not to kip or swing to gain momentum while doing the exercise. Try to eliminate this as soon as possible, as it may turn into a habbit and will be hard to unlearn. Don't drop your body rapidly after your chin is over the bar because this may lead to injuries. Also, try to engage your abdominal muscles during the exercise. This exercise can be performed with overhand grip (recommended) and neutral or mixed grip. Exercise should be performed on a bar or gymnastic rings. Exhale as you pull your body up and inhale when you lower yourself back. This variation puts a lot of stress on your shoulder muscles, so if you have any injuries or feel pain in your shoulders, try different variation.
This variation is harder than close grip pull ups, because it puts more strain on your lats (back) muscles. In wide grip pull ups you have shorter range of motion than in close grip pull ups. This exercise can be combined with other variations of pull ups for example: L pull up, rear pull up.
