Leg extensions can be effective for building muscle in the quadriceps, particularly when performed with appropriate resistance and progressive overload. Here's how leg extensions can contribute to muscle growth:

Targeted quadriceps activation: Leg extensions isolate the quadriceps muscles, placing direct tension and load on them. This focused activation can help stimulate muscle growth in the quadriceps.

Muscle damage and hypertrophy: Leg extensions, when performed with challenging weights, can cause muscle damage, which is a natural part of the muscle-building process. This damage, when followed by proper rest and nutrition, leads to muscle repair and growth (hypertrophy).

Progressive overload: To build muscle, it's important to progressively increase the demands placed on your muscles over time. You can achieve this by gradually increasing the resistance or weight used during leg extensions. Progressive overload stimulates the muscles to adapt and grow stronger and larger.

Volume and intensity: Performing leg extensions with an appropriate number of sets and repetitions can contribute to muscle growth. Higher training volumes (total sets and reps) and intensities (challenging weights) can lead to greater muscle stimulation and adaptation.

Supplementing overall leg training: While leg extensions primarily target the quadriceps, they can be a valuable addition to an overall leg training routine. Combining leg extensions with compound exercises like squats, lunges, and deadlifts provides a more comprehensive leg workout, engaging multiple muscles and promoting overall leg strength and muscle development.

It's important to note that building muscle is not solely reliant on a single exercise. A well-rounded strength training program that includes a variety of exercises, proper nutrition, adequate rest, and consistency is crucial for optimal muscle growth. Consulting with a fitness professional can help you design an effective program tailored to your goals and abilities.
