Band Assisted Pull Ups
Can’t do a pull up yet? No problem! Although calisthenics is all about just using your bodyweight, sometimes buying certain equipment can help you excel at calisthenics.
Go to your local walmart or buy online some exercise bands.
Wrap it around your bar and place one foot inside. Then do a pull up. With the bands it will help bring you up and build the strength needed to do a pull up without them.
