About this machine

Leg extension gives the quadriceps focused work without needing to balance a bar or hold the torso in position. Use it when you want extra front-thigh work after a compound leg exercise, or when you need to compare control between sides.

Muscles worked

  • Main load: Front thigh.
  • Stabilization: trunk muscles help hold position.
  • Should not hurt: joints or lower back. If they do, reduce load and check setup.

How to set up

  1. For the Pure Kraft Leg Extension, first check its source-listed detail: uses a foot support or platform to fix the position.
  2. Sit deep in the seat and keep the pelvis against the pad.
  3. Line the knee up with the machine lever axis.
  4. Place the roller on the lower shin, not on the foot.
  5. Choose a range where the knee extends smoothly.

How to perform

Main exercise: seated leg extension.

  1. On the Pure Kraft Leg Extension, move smoothly through this model's working path.
  2. Pause at the top without snapping into lockout.
  3. Lower the roller slowly while staying against the backrest.
  4. End the set if the pelvis starts lifting from the seat.

Common mistakes

  • Putting the roller on the foot instead of the shin.
  • Letting the knee sit away from the lever axis.
  • Kicking the weight or slamming into the top position.
  • Using a load that lifts the pelvis from the seat.
  • Ignoring this model-specific detail: uses a foot support or platform to fix the position.
