FAQs
How do I change the resistance?
The bendable spring has three adjustment stages, giving roughly 30-50 kg of resistance. Set it lower to start and move up as you get stronger.
Which muscles does it work?
Mainly the chest, plus biceps, triceps, shoulders and forearms. You squeeze the sprung arms together against resistance, so it trains the same pressing and squeezing movements as a chest press or pec deck.
Is it suitable for beginners?
Yes. Start on the lowest setting with slow, controlled reps. If a full-range squeeze is too hard at first, use partial reps and build up.
What is it made of?
A steel frame with a foam-wrapped U-shaped handle and an upgradeable steel spring. It comes in Blue/Black or Red/Black.
Can I use it for more than chest work?
Yes - it also works for shoulder presses, isometric holds and light back and arm exercises depending on how you position and press against it.
