How to do the Dumbbell Straight-Arm Crunch
Start by lying flat on your back on a comfortable surface with your knees bent and feet flat on the floor.
Hold a dumbbell with both hands and extend your arms straight above your chest. Keep your arms close to your ears throughout the movement to isolate the abdominal muscles effectively.
Engage your core and gently tuck your chin to your chest to maintain a neutral neck position.
Exhale as you lift your upper body off the ground, performing a crunch movement. Your arms should remain straight as you raise your shoulders and upper back off the floor.
Inhale as you slowly lower your upper body back to the starting position, maintaining control and keeping your arms extended.
It's important to perform the movement with control and avoid using momentum to lift your upper body. Focus on using your abdominal muscles to perform the crunch. Keep the motion smooth and continuous, and adjust the weight of the dumbbell according to your fitness level.
