The JAWS Legacy 2-in-1 Standing Leg Extension & Leg Curl Machine is an exceptional piece of gym equipment that combines two essential exercises into one, albeit the standing variant of a leg curl is less common, compared to seated and laying, and the standing variant of a leg extension has never had a purpose-made machine, before now.

With its robust build and intuitive design, this machine is engineered to withstand rigorous workouts while ensuring user comfort and safety.

Incorporating the JAWS Legacy machine into your workout routine can provide a plethora of benefits, making it an invaluable addition to your fitness arsenal.

Enhanced Muscle Development

How to Use the JAWS Legacy Machine for Maximum Results

To make the most out of your workouts with the JAWS Legacy 2-in-1 Standing Leg Extension & Leg Curl Machine, it's important to use it correctly. Here's a step-by-step guide to help you get started.

Performing Standing Leg Extensions

1. Set the Machine: Set the machine up for the standing leg extension position, as illustrated, with the roller up high and the weight horn positioned toward the base.  

2. Position Yourself: Stand upright, with one foot on the designated plate and the other foot (working leg) with laces on the roller, knee bent, and thigh pressed against the thigh pad, gripping the handles for support. 

3. Execute the Exercise: Extend your lower leg forward at the knee, keeping your upper body stable. Hold the position for a moment before returning to the starting position. Focus on controlled movements to maximise muscle tension and growth.

4. Repetitions: Perform 10+ repetitions per set, depending on your fitness level. Some athletes may wish to perform higher reps, rather than increase weight. Adjust the number of sets, reps, and weight as you progress to continually challenge your muscles.

Performing Standing Leg Curls

1. Set the Machine: Set the machine up for the standing leg curl position, as illustrated, with the roller low and the weight horn positioned higher up.  

2. Position Yourself: Stand upright, with one foot on the footplate, holding the handles for balance. Keep your core engaged to maintain stability throughout the movement. Place the ankle of your working lower leg against the padded roller. Maintain a straight posture to ensure balanced weight distribution.

3. Execute the Exercise: Curl your leg backward, bringing your heel towards your glutes. Hold briefly before returning to the start. Concentrate on slow, deliberate movements to enhance muscle activation.

4. Repetitions: Aim for 10-15 repetitions per set. As you build strength, consider increasing the resistance or adding more sets to your routine.
