What matters on this model
- Isolates the glutes through backward hip extension.
- The knee pad is steplessly adjustable so the support leg stays stable.
- The support surface adjusts through 12 positions for different heights and thigh lengths.
- Two handles help stabilize the torso and stop the pelvis from rotating during the kick.
- The weight stack makes the load easier to dose than free standing leg swings.
Why use it
Use it for targeted glute training, preparation for hip-extension work, or a glute finisher after squats, leg presses, or lunges. It is especially useful when you want to remove body swinging and train one side at a time.
Muscles worked
- Main load: gluteus maximus of the working leg.
- Support: hamstrings assist hip extension, while trunk muscles keep the pelvis steady.
- Should not hurt: lower back or support knee. If they do, reduce the load and check support height.
How to set up
- Adjust the knee pad so the support knee rests softly and securely without joint pressure.
- Choose one of the 12 support-surface positions so your pelvis stays level and the working leg can move backward freely.
- Place the working foot on the lever or platform as designed, keeping the heel stable.
- Hold both handles, square the shoulders and pelvis, and avoid arching the lower back.
- Start light and check that the movement comes from the glute, not from a torso swing.
How to perform
- Exhale and drive the working leg backward while keeping the torso and pelvis still.
- Pause briefly at the end range and squeeze the glute without overextending the lower back.
- Inhale and return the leg forward slowly, keeping control of the weight.
- Do not rotate the pelvis toward the working side or lean your weight into the handles.
- After the set, change sides and repeat the setup for the other leg.
Common mistakes
- Using too much weight, turning the movement into a torso jerk instead of a glute contraction.
- Arching the lower back at the top instead of extending the hip.
- Rotating the pelvis outward, which makes the path diagonal and less controlled.
- Returning too fast, so the weight moves itself and the muscle loses tension.
