Mastering the Leg Extension Crunch for a Stronger Core and Thighs

The Leg Extension Crunch is a powerful exercise that effectively targets the quadriceps and the rectus abdominis, making it an excellent addition to any fitness routine focused on strengthening the thighs and core. Utilizing a stability ball, this exercise combines the benefits of leg extensions and abdominal crunches to maximize your workout results.

To perform the Leg Extension Crunch:

  1. Begin by sitting on a stability ball with your feet flat on the floor, about hip-width apart.
  2. Gradually roll down the ball until your lower back is supported, and your upper body is positioned vertically.
  3. Engage your core muscles as you lift your legs from the ground, extending them out in front of you while keeping your knees straight.
  4. As you extend your legs, simultaneously perform a crunch by bringing your torso upward toward your thighs.
  5. Hold for a moment at the top of the movement, then slowly lower both your upper body and legs back to the starting position.

Some tips to enhance your performance and safety during the Leg Extension Crunch include:

  • Always maintain a neutral spine throughout the movement to avoid strain.
