The weighted leg extension crunch is a compound exercise that involves a combination of a crunch and a leg extension with added weight. It primarily benefits individuals looking to strengthen their core, improve their mobility, and enhance their athletic performance.

🧠 Anatomy and Muscles Worked

Primary Movers

• Rectus Abdominis: This is your "six-pack" muscle that contracts during the crunching motion.
• Hip Flexors: These muscles engage during the leg extension part of the exercise.

Secondary/Supporting

• Quadriceps: These large muscles in your thighs assist during the leg extension.

✅ Benefits of the Weighted Leg Extension Crunch

2. Enhanced Mobility: By working the hip flexors and quadriceps, it aids in improving your overall mobility.
3. Improved Athletic Performance: A strong core and good mobility are essential for better athletic performance.
4. Versatility: Can be performed with various weights and at different speeds to suit your fitness level and goals.
5. Full Body Workout: It's a compound movement that works multiple muscle groups at once.
