Basic Pull Up
To do a Basic Pull Up, stand with a pull up bar overhead and in front of you. Grab the bar with your palms facing away and about shoulder-width apart.
Hang from the bar with your body hanging straight down. Press your chest out and even lean back ever so slightly.
Then pull your chin up above the bar, leading with your chest. Drive your elbows down as you lead with your chest.
Once you get your chin above the bar, lower back down, fully extending your arms.
Try not to swing a ton or kick.
Repeat, pulling yourself back up to the bar, leading with your chest.
