Unlocking lower body strength with the BLK BOX Pin Select Leg Extension/Curl

Strong legs aren’t just about aesthetics - they are the foundation of power, stability, and injury prevention. Whether you're training for sport, building strength, or just looking to move better, a strong lower body makes all the difference.

The BLK BOX Pin Select Leg Extension/Curl is designed to help you train smarter. By isolating the quads and hamstrings, it delivers targeted muscle activation that squats and deadlifts alone can’t achieve.

Why leg extensions and curls matter

Big lifts like squats and lunges are essential, but they don’t allow for complete isolation of key muscle groups. That’s where a leg extension/curl machine comes in. Here’s why it deserves a place in your gym:

• Builds stronger, more defined quads and hamstrings by focusing on isolated muscle contractions.
• Improves knee stability and joint health by strengthening supporting muscles.
• Helps with rehabilitation and recovery, allowing controlled movement for rebuilding strength.
• Makes progressive overload easier with simple weight adjustments to fine-tune resistance.

Engineered for performance

At BLK BOX, we build equipment that lasts. The Pin Select Leg Extension/Curl is designed to handle heavy, daily use. Here’s what sets it apart:

• 86kg weight stack, providing resistance for all strength levels.
• 1:1 resistance ratio, delivering consistent tension throughout every rep.
• Magnetic selector pin for quick, secure weight adjustments.
• Ergonomic design that promotes proper form and reduces strain on the joints.
• High-density foam padding that offers comfort and durability over time.

How to train for maximum results

Whether your goal is strength, muscle growth, or endurance, this machine can be programmed to fit your needs. Here’s how to get the most out of it:

For strength and power

Perform 4 sets of 8-10 reps at 75-85% of your max weight. Focus on controlled movement and explosive contractions.

For muscle growth

Perform 3-4 sets of 10-12 reps, with a slow lowering phase of 3-4 seconds to maximise muscle tension.

For rehabilitation and injury prevention

Use lighter weights with 15-20 reps per set, focusing on full range of motion and controlled movement.

Why this machine belongs in your facility

Whether you run a commercial gym, training facility, or want to upgrade your home gym setup, the BLK BOX Pin Select Leg Extension/Curl is built for performance. It’s an investment in quality, durability, and long-term results.
