This is especially true for pullups. This is another compound-muscle exercise that’s great for working your back and arms. You will, however, need to purchase a pull-bar of some kind, but they usually come pretty cheap ($20 to $30 at most sports and athletic stores), and most can be set up in any door frame. To perform a correct pullup, reach up and grab your pull-up bar in an overhand grip and hang. This is how you should start every repetition. From the hang, pull yourself up until your chin is above the bar. Then slowly let yourself down. For a chinup, simply grab the bar in an underhand grip.
