Exercise Information

Leg Extensions are a resistance training exercise that targets the muscles in the lower body. This exercise involves using a resistance band or weight machine to add resistance throughout the entire range of motion, increasing muscle activation in the targeted muscle groups. Let’s dive into some general information about this exercise:

Level

Leg Extensions are a beginner-level exercise that is suitable for individuals of all fitness levels.

Equipment

To perform Leg Extensions, you will need a resistance band or weight machine.

Type of Exercise

Leg Extensions are an isolation exercise that targets the muscles in the lower body, involving a single-joint movement that mainly focuses on one specific muscle group.

Leg Extensions: Working Muscles

The Leg Extension is an isolation exercise that primarily targets the muscles of the lower body. This exercise involves using a leg extension machine to add resistance to the traditional leg extension motion. In this section, we will discuss the primary and secondary muscle groups that are involved during the Leg Extension exercise.

Primary Muscle Group: Quads

The primary muscle group targeted during the Leg Extension exercise is the quadriceps, otherwise known as the quads. These muscles are responsible for extending the knee joint, which is the primary motion of the Leg Extension exercise.

Secondary Muscle Group: Glutes and Hamstrings

In addition to the primary muscle group, the Leg Extension exercise also engages the muscles of the glutes and hamstrings. The glutes and hamstrings work to stabilize the knee joint and maintain proper posture during the exercise.

By engaging both the primary and secondary muscle groups, the Leg Extension exercise provides a comprehensive lower body workout. This makes it an effective exercise for building lower body muscle strength and size, improving posture and stability, and developing functional fitness for activities in daily life.

Track Your Progress

To ensure you are making progress and staying on track with your Leg Extension workouts, it is important to track your progress. Keep a workout journal or use a fitness app to log the weight, reps, and sets for each exercise.
