Adjustable Hand Trainer 5-165 kg Steel Spring

Your grip strength fades just when every movement counts.

Anyone who works daily with dumbbells, climbing routes, or instruments knows the problem: hands tire quickly, control diminishes. This hand trainer with continuously adjustable resistance from 5 to 165 kg solves exactly this problem. Using a knurled screw, the resistance can be set precisely – from the first gentle pull to maximum effort for advanced users. Weighing only 367 g, it can be used anywhere: at the desk, in the sports bag, or while traveling. 

Benefits

• No more training interruptions due to declining grip strength: The continuously adjustable resistance grows with your progress – you don’t need to switch devices, just adjust the resistance.
• No repacking, no searching: Weighing only 367 g, the trainer fits in any bag – you can train whenever you have a free minute without any extra effort.
• No question of durability: The high-quality steel spring provides consistent resistance with every cycle and is designed for thousands of repetitions – you don’t have to worry about when the device will wear out.

Specifications

• Resistance range: 5–165 kg, continuously adjustable
• Weight: 367 g
• Material: Steel with steel spring, plastic housing
• Color: Black (with orange steel spring)
• Grip shape: Ergonomically curved pistol grip with a ribbed surface

Application

1. Adjusting the resistance: Turn the knurled screw on the trainer to the desired resistance – from light to very challenging.
2. Exercise: Hold the ergonomic grip firmly and perform smooth closing and opening movements – 3 sets of 15 repetitions each are a good starting point.
3. Progression: Increase the resistance gradually every two weeks once the current setting no longer causes fatigue.

Pro tip: Train alternately with your eyes closed – this sharpens body awareness and activates additional stabilizing muscles in the forearm that often go unnoticed during regular training.
