#4 Start With Chin-Ups
Chin-ups are somewhat easier than pull-ups due to the difference in grip (chin-ups use an underhanded grip), which allows for greater use of your biceps. Practicing with chin-ups will help you build the strength you need to do proper pull-ups.
#5 Start in the Right Position
Instead of starting in a dead hang, which places more strain on your tendons, make sure that you’re supporting your weight with your muscles when you get onto the pull-up bar. It’s safer and makes it easier to engage your muscles when you start your set.
#6 Pay Attention to Your Elbows
Keep a slight bend in your elbows throughout your whole set; locking them places dangerous strain on your ligaments and makes it harder to keep your arms in motion. As you do your pull-ups, drive down with your elbows, which will engage the muscles in your back.
#7 Improve Your Grip
You’re not going to get very far with pull-ups if your hands aren’t strong enough to hold onto the bar throughout your whole set. You can use a specific grip strengthening tool, or work grip-focused exercises into your lifting routine.
