The triceps crunch is a trunk flexion exercise that increases core strength, while targeting lower abdominal and hip flexor regions. Adding the dumbbells increases the intensity of this move.
Lie face-up on the floor holding a pair of dumbbells directly over your chest with the palms facing each other. Bend your knees to a 90-degree angle, and lift the feet off of the ground so that your thighs are just shy of perpendicular to the ground.
Keep your elbows pointed forward as you lower the dumbbells beside your ears while extending your legs out. Then return to the starting position by extending your arms overhead while at the same time bringing your knees back towards your chest.
Don't arch your lower back as you extend your legs.
Don't allow your elbows to point out towards the sides as you lower the dumbbells.
Don't allow the dumbbells to touch the floor as you lower them behind your head.
