Gorilla Chin/Crunch

How to perform

1. 01Hang from a chin-up bar using an underhand grip (palms facing you) that is slightly wider than shoulder width.
2. 02Now bend your knees at a 90 degree angle so that the calves are parallel to the floor while the thighs remain perpendicular to it. This will be your starting position.
3. 03As you exhale, pull yourself up while crunching your knees up at the same time until your knees are at chest level. You will stop going up as soon as your nose is at the same level as the bar. Tip: When you get to this point you should also be finishing the crunch at the same time.
4. 04Slowly start to inhale as you return to the starting position.
5. 05Repeat for the recommended amount of repetitions.

Form cues

• —Brace your core before the first rep and keep it braced.
• —Lead with the elbows and finish by squeezing the target muscle.
• —Control the lowering phase — that is where most of the growth stimulus lives.

Common mistakes

• —Using momentum instead of the target muscle.
• —Cutting the range of motion short to add load.
• —Adding weight before the movement pattern is clean.
