Getting your next view ready…
The Gorilla Chin/Crunch primarily works the abdominals, with the biceps and lats supporting the movement. It is a strength movement that needs no equipment.

1 / 2How to
Movement instructions
Hang from a chin-up bar using an underhand grip (palms facing you) that is slightly wider than shoulder width.
Now 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.
As 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.
Slowly start to inhale as you return to the starting position.
Repeat for the recommended amount of repetitions.
Technique guidance
Exhale through the abdominal effort and inhale during the controlled return. Keep the neck relaxed and do not hold your breath.
General guidance based on the exercise and equipment. It is not personal coaching or medical advice.
Your progress
Keep the same exercise variation, range of motion and recording method when comparing Gorilla Chin/Crunch sessions.
Repetitions and completed sets.
Example: 10, 9 and 8 completed reps. Keep each set separate instead of recording only the total.
Compare repetitions using the same variation and range. A different variation needs its own history; extra reps are not directly comparable if the movement changes.
