RussianAbout this machine
Leg press and squat machines load the legs heavily while supporting the torso. They work well as the main part of a leg session when the pelvis and lower back stay supported. Foot position can change emphasis, but it should never compromise knee direction or range control.
Exercise options
- Squat in the intended configuration: quadriceps and glutes; trunk muscles stabilize.
- Lunge in the intended configuration: quadriceps and glutes of the working leg; adductors and trunk stabilize.
- Calf raise: gastrocnemius and soleus.
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
- For the Pure Kraft Squat Machine, first check its source-listed detail: targets the calves.
- Adjust the seat, platform, or shoulder supports for your height.
- Place the feet symmetrically and check knee direction.
- Choose a start depth where the pelvis stays supported.
- Release stops only after the start position is stable.
How to perform
Main exercise: squat, lunge, or calf raise only in the machine's intended configuration.
- On the Pure Kraft Squat Machine, move smoothly through this model's working path.
- Keep the knees tracking with the feet.
- Do not bounce out of the bottom position.
- Return under control without snapping the joints locked.
Common mistakes
- Letting the knees collapse inward or drift without control.
- Lifting the heels from the platform.
- Going so deep that the pelvis rounds away from support.
- Locking the knees harshly at the end.
- Ignoring this model-specific detail: targets the calves.
