This is my first workout video, whoooooo!
The most important part of a pullup is not pausing to hang at the bottom. Pausing at the bottom causes inertia, tires you out. It actually gets kind of addicting to try to go down and up without a pause.
This can be applied to other repetitive exercises such as pushups, situps, etc.
A side note: my dad made this pullup bar. Isn’t it sweet?
