With ArmKraft™, you bring versatile strength training right to your home. The U-shaped spring trainer combines a robust steel construction with adjustable resistance, allowing for various pushing, pulling, and rotational movements for a diverse upper body workout.

Depending on the exercise, arms, chest, shoulders, biceps, triceps, and back can be specifically engaged in the movement. Thanks to its compact design, the trainer is ideal for short workout sessions at home and can be easily taken along when on the go.

ArmKraft™ offers three adjustable resistance levels, allowing you to tailor the load to your exercise and personal training level. Start with a lighter setting and gradually increase the resistance when you want to train more intensely.
This way, you don't need a separate device for each training level and can perform different exercises with the same trainer.


The core of the trainer is the integrated steel spring construction. It generates controlled resistance during movement and then returns to its original position.
With different grip positions and movement directions, ArmKraft™ can be used in a versatile manner. Instead of focusing on just one muscle group, you can integrate various exercises into your personal training routine.

The elongated grips are padded with foam and designed for a stable hold. The textured, non-slip surface makes it easier to control the device, especially when hands become moist during longer training sessions.
The U-shape allows for a natural grip position and provides enough space to squeeze, pull apart, or twist the trainer as needed, depending on the exercise.
For ArmKraft™, you don't need a large fitness device or a dedicated training room. With its compact dimensions, the spring trainer can be easily stored after training and brought out again when needed.
It is also practical for travel or short training sessions in between, allowing you to flexibly integrate your resistance training into your daily routine.

1. Adjust Resistance: First, select a resistance level suitable for your current training level. Preferably start with a lower load for new exercises.
2. Grip Securely: Hold both padded grips firmly and maintain a controlled body posture.
3. Perform Movement: Slowly and controlled, press, pull, or move the trainer according to the chosen exercise. Avoid jerky movements and allow the spring to return to its starting position just as controlled.
4. Vary Training: Change grip position, movement direction, or resistance to target different areas of the upper body.
