The BUILT Strength Infinite Series Iso-Lateral Kneeling Leg Curl trains each hamstring independently — one leg curls while the other rests supported on a pivoting knee cradle, eliminating the bilateral compensation that standard lying leg curls allow to go unchecked. The kneeling position lengthens the hamstring from the hip, placing it under stretch before the curl even begins and increasing the range of effective tension through each rep.

Starting resistance of just 8 lb per arm makes the movement genuinely accessible for technique work and rehabilitation, while a 4 × 25 lb max capacity supports meaningful progressive loading for strength development. Four integrated weight horns keep plates on the machine and within reach — no hunting across the floor between sets. Heavy-duty construction in a compact 40" × 54" footprint makes this machine an efficient addition to any commercial or performance training floor.

Gastrocnemius Glutes

Iso-Lateral Unilateral Movement
Each leg curls independently — preventing the stronger hamstring from compensating for the weaker, building true bilateral balance, and allowing targeted single-leg work without changing the machine setup.
Pivoting Knee Cradle Pad
A pivoting cradle supports the non-working leg in a stable, comfortable position while the active leg moves freely through the full curl — keeping the body braced and the working hamstring isolated throughout.
Kneeling Position for Extended Range
The kneeling stance lengthens the hamstring from the hip joint before the curl begins — placing the muscle under stretch at the start of each rep and increasing the range of effective tension compared to a lying curl position.
Plate-Loaded — 8 lb to 100 lb Per Arm
Starting resistance of 8 lb per arm supports technique work and rehabilitation loads. Max capacity of 4 × 25 lb plates per arm reaches 100 lb per side for athletes building serious hamstring strength.
4 Integrated Weight Horns
On-machine plate storage keeps the surrounding floor clear and plates within reach — load and strip between sets without leaving the station or searching the gym floor mid-session.
