One Arm Trainer
€99,00
Regular price €90,00The One Arm Trainer was designed to efficiently train one arm - right after the other - in a way that no traditional fingerboard can do.
- How To Use The One Arm Trainer
-
Installation guide:
- Step 1: Basic handles assembly
- Step 2: Attach rope to O.A.T
- Step 3: Rope length adjuster installation
- Step 4: Hang it all up
How it works:
- The One Arm Trainer hangs up on one rope
- By keeping the board horizontal while training, you can maximize the efficiency and achieve the best results from your workout
- By changing the position of the rope, you can increase the strength needed in one arm (and decrease the strength needed in the other)
- Move the rope away from the center to gradually increase the difficulty of hanging or pulling up on the One Arm Trainer
Benefits:
- Gradually increase and monitor your strength!
- The pegs give you immediate feedback on your progress day-to-day!
- No crimp, sloper, pinch or jug will be left unchallenged
- The basic handles, cones, cylinders, and even the Maxgrip or Maxgrip Hybrid can be used to cross train your grip strength!
- Train Anywhere!
- It's easy to bring the One Arm Trainer to the gym, crag, park, or even a friend's house!
*You will need the basic handles to use the Maxgrip or Maxgrip Hybrid
Sustainability:
The rubberwood we use for these products is from a completely sustainable source! Currently, rubber plantation trees are harvested for wood after they complete the latex producing cycle, when they are 25 to 30 years old.
When the latex yields become extremely low, the trees are then felled, and new trees are usually planted. This makes rubberwood 'eco-friendly' because the wood is harvested from a renewable source.
One Arm Trainer Includes:
- One arm trainer (wood) + selected holds
- 1 rope + rope length adjuster

add-ons
The maxgrips and maxgrip hybrid can be inserted in the one arm trainer. This way you can improve your crimp and sloper strength as well.
insert different holds
the one arm trainer full combo comes with 4 sets of holds. Each set working your forearms differently. check out our "how to use" to see the function of the grips.
increase difficulty by moving the rope to the side
When the rope is centered, your weight is distributed evenly between left and right arm. when the rope is placed more to the side, there will be more weight on the arm and hand on that side as long as you keep the O.AT levelled.
