Reach up and grab a pull-up bar with a wide overhand grip (palms facing forward). Your hands should be more than shoulder-width apart but not too wide.
ring your shoulders back, engage your abs, and lift your feet off the floor to suspend yourself in the air. Keep your feet together or bend your knees and interlock your lower legs.
Take a breath and pull yourself up in one fluid motion. Go up until your chin is over the bar and hold for a moment as you exhale.
