Crunch (legs on stability ball)
The crunch (legs on stability ball) is a dynamic abdominal exercise that targets your rectus abdominis, obliques, and hip flexors. This variation of the traditional crunch adds an extra challenge by incorporating a stability ball, which requires greater core stabilization and engages more muscle fibers. To perform this exercise, position yourself with your lower back on the stability ball and your feet placed firmly on the floor. Your knees should be bent at a 90-degree angle, with your thighs parallel to the floor. Place your hands lightly behind your head, elbows pointing out to the sides. From this starting position, engage your core muscles by drawing your belly button in towards your spine. Using your abdominal muscles, lift your shoulder blades off the ball while maintaining a neutral neck position. Aim to bring your chest closer to your knees, avoiding excessive pulling on your neck. As you lift, exhale and focus on squeezing your abs to achieve a maximum contraction. Hold for a brief moment and then slowly lower back down to the starting position while inhaling. Remember to maintain control throughout the movement, avoiding any jerking or swinging motions. When performing the crunch on a stability ball, the added instability challenges your balance and engages more of your stabilizing muscles. This can lead to improved core strength, better posture, and enhanced functional stability for everyday movements. As with any exercise, it's important to maintain proper form and listen to your body. If you experience any discomfort or pain, modify the exercise or consult with a fitness professional to ensure you're performing it correctly. Incorporate the crunch (legs on stability ball) into your abdominal workout routine to strengthen and sculpt your midsection for a more defined and functional core.
Instructions
- Start by lying on your back on a mat with your feet hip-width apart, and place a stability ball between your lower legs.
- Extend your arms out in front of you or lightly place your fingertips behind your ears, without pulling on your neck.
- Slowly lift your head, neck, and shoulders off the mat, while simultaneously squeezing the stability ball between your legs.
- Engage your abdominal muscles and exhale as you curl your upper body towards your knees.
- Hold the contracted position for a brief pause, and remember to keep your lower back pressed into the mat throughout the exercise.
- Inhale as you slowly lower your upper body back down to the starting position, maintaining control.
- Repeat for the recommended number of repetitions.
