Pull Up

Pull ups are a great exercise to strengthen your upper body and core muscles. Here are some steps to perform them correctly:

1. Grab a pull up bar with your hands shoulder-width apart and palms facing away from you.
2. Pull your shoulder blades down and back, and engage your core muscles.
3. Pull yourself up until your chin is above the bar, keeping your elbows close to your body.
4. Lower yourself slowly and with control until your arms are fully extended.
5. Repeat as many times as you can, resting as needed between sets.
