RussianAbout this machine
This is isolation work for the arms. It does not replace presses and pulls; it complements them when you want separate biceps or triceps work. The guide and pad make a moderate load and a controlled elbow position more important than heavier weight.
Muscles worked
- Main load: Biceps.
- 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 Biceps Curl Dual, first check its source-listed detail: has a source-listed target muscle focus.
- Set the seat or pad so the elbow lines up with the working axis.
- Hold the handles without bending the wrists back.
- Keep the upper arms or forearms against the support when provided.
- Choose a load that does not require body swing.
How to perform
Main exercise: biceps curl.
- On the Pure Kraft Biceps Curl Dual, move smoothly through this model's working path.

Common mistakes
