Only in Gorilla Chin/Crunch
Instructions
3/4 Sit-Up
Lie down on the floor and secure your feet. Your legs should be bent at the knees.
Place your hands behind or to the side of your head. You will begin with your back on the ground. This will be your starting position.
Flex your hips and spine to raise your torso toward your knees.
At the top of the contraction your torso should be perpendicular to the ground. Reverse the motion, going only ¾ of the way down.
Repeat for the recommended amount of repetitions.
Gorilla Chin/Crunch
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.
Verdict
Both exercises target the abdominals. 3/4 Sit-Up is a beginner exercise using bodyweight, while Gorilla Chin/Crunch is intermediate and uses bodyweight. Choose 3/4 Sit-Up if you're looking for a more accessible option, or Gorilla Chin/Crunch for a greater challenge.
