Element - CARBON BLACK 9019 Leg Extension / Leg Curl 250lbs with Dark Shroud

Two Essential Leg Exercises in One Machine

The Element CARBON BLACK 9019 combines two of the most popular selectorized lower-body exercises into a single station:

Leg Extension – Quadriceps

The seated leg extension involves extending the knees against resistance and primarily targets the quadriceps muscles on the front of the thighs. This controlled isolation movement is commonly used to strengthen the rectus femoris, vastus lateralis and the quadriceps muscle group. Leg extensions are a staple exercise in commercial strength-training circuits and lower-body workouts.

Seated Leg Curl – Hamstrings

The seated leg curl involves bending the knees against resistance to target the muscles on the back of the thighs. The movement primarily trains the hamstrings, including the biceps femoris and semitendinosus.

Combining leg extensions and leg curls in one machine allows users to train opposing muscle groups of the thigh from the same selectorized station.

Why Choose a Leg Extension / Leg Curl Machine?

Leg extensions and leg curls are two of the most widely used isolation exercises for lower-body strength training. A traditional commercial gym may use one machine for the quadriceps and another machine for the hamstrings. The Element CARBON BLACK 9019 combines both functions into a single selectorized station, giving users dedicated training for both sides of the thigh while helping fitness facilities make more efficient use of available floor space.

Balanced Quad and Hamstring Training

The quadriceps and hamstrings perform opposing actions around the knee. The CARBON BLACK 9019 allows users to train both muscle groups using two controlled selectorized movements: Leg Extension — emphasizes the quadriceps on the front of the thigh, and Leg Curl — emphasizes the hamstrings on the back of the thigh. Providing both exercises from the same station makes the 9019 an excellent addition to a complete lower-body strength circuit.

Commercial 250 lb Weight Stack

This version of the CARBON BLACK 9019 includes a substantial 250 lb selectorized weight stack, providing resistance suitable for users across a broad range of strength levels. Resistance can be changed quickly using the selector pin, making the machine especially convenient in busy commercial and shared fitness environments. There is no need to load or unload weight plates between users or exercises.

Save Valuable Gym Floor Space

Installing separate commercial leg extension and leg curl machines requires additional floor space. The CARBON BLACK 9019 combines both exercises into one dual-function machine, making it particularly useful for condominium gyms, hotels, corporate fitness centres, schools, personal training studios and facilities with limited strength-training space. It is equally suitable for larger commercial gyms looking to add versatile dual-function equipment to their strength circuit.
