If you want to be able to do a full pull up, you have to do pull ups.
BUT only doing assisted isn't enough. You NEED to take on your own bodyweight and you need to spend more time under tension.
That is where Eccentric Pull Ups come in.
So what are Eccentric Pull Ups?
Eccentric Pull Ups are pull ups that focus on a slow lower back down. You want to try to take as long as possible to slowly extend back down.
With Eccentric Pull Ups, you can jump, use your feet or pull up to the top, but the key is to take on your own bodyweight for the lower back down. This will help you learn how to hold your own weight, which is key.
If you never take on your own bodyweight, you'll just get used to assistance and never learn how to engage your back and core as you perform the move.
AND by focusing on the eccentric portion of the movement, you can also break down more muscle tissue aka force your muscles to regrow stronger!
Studies have shown that slower tempos on the eccentric portion of a move can cause more muscle damage. And more muscle damage means your body is forced to repair and rebuild stronger!
This is why Eccentric Pull Ups are KEY #2. Using these you can gain more strength, learn how to handle your own bodyweight and spend more time under tension to help you get FASTER results.
So to recap...First you activate your back so that your back muscles are actually working. Then you use those back muscles while taking on your own bodyweight during Eccentric Pull Ups.
You focus on doing MORE PULL UPS, but at the same time LOWER REPS.
How the heck can you accomplish both at the same time!?
