The One Arm Trainer was designed to efficiently train one arm - right after the other - in a way that no traditional fingerboard can do.

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


  • 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


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

train smarter, not harder
When you can't send it, train it!

Climbing throws a variety of different moves, holds, and challenges at you...

That's why you need a tool designed to take on the toughest projects.

Why The One Arm Trainer?

Fingerboards are great for static muscle training, but we’ve introduced a dynamic innovation to revolutionize the climbing industry.

The One Arm Trainer can train your upper body and grip strength while remaining fully versatile and allowing for progressive difficulty levels.

Don't take our word for it


In my climbing gym, this tool is a must have! Awesome how you can increase training intensity so easily.


Kortrijk, BE


It's refreshing to see such a revolutionary training tool for climbers. I feel like there hasn't been much innovation or new tools in the climbing community in a while. We've been using the same old stuff forever


Arkansas, USA


I've been working on some hard projects and can definitely feel the send coming after training with the One Arm Trainer. It has a well earned spot in my training routine


Kortrijk, BE


As a Personal Trainer, I love using the One Arm Trainer in my trainings. At first, people struggle to keep it balanced. After a couple of weeks they can not only keep it stable but also increase the difficulty significantly


Ghent, BE


After taking a break from climbing, this tool will bring me back up to speed in no time. Love it


Paris, FR


I'm using the "OAT" for improving balance and muscle coordination mainly. stabilizing the board and pulling up is already a big challenge on these grips


London, UK


When doing an archer pull up, your body will move diagonally. This means that the weight on each arm/hand will vary depending on where you are in the pull up. The OAT makes you move vertically which ensures that you train the entire motion with constant weight, just like when you do a one arm pull up.

The Maxgrips are not required for the OAT; however, they bring crimps, slopers and jugs to the table.

If you want to train with more than just pinches, the Maxgrip or Maxgrip Hybrid is a great way to do it.

It will aid you for sure!

Not enough data to say with absolute certainty. Probably not though...

Maxgrip Hybrid

Regular price€89,00
Tax included. Shipping calculated at checkout.

We are incredibly proud to present to you, the Maxgrip Hybrid! It offers the ultimate balance between looks, weight, innovation and functionality!

Building upon the expierience of producing our popular traditional Maxgrips for nearly 5 years now, it was a natural step to design and produce a wooden version of them!

Lightweight, extra skin friendly, made from eco-friendly rubberwood, combined with the tested design and functionality of the traditional Maxgrips, this tool is a must-have for any passionate climber!

With 6 different gripping positions this hang hold is truly multifunctional and an excellent choice for both core tension and upper body strength exercises. Whether you want your holds up high up or down low to the floor, the rope length adjusters allow you to quickly change the rope length for various exercises. For instance:

  • Training with uneven loads by hanging one hold higher than the other.
  • Push-up exercises with your hands on the Maxgrips offer a great challenge, activating your stabilizing muscles.
  • Suspension trainer setup in order to train your antagonists and work on your posture.

Just like the Rockblob, the Maxgrip is a great solution for your mobile climbing gym or as a warm-up tool. You can easily take them on a travel, to a crag, to a competition or simply to the gym and suspend them to a tree branch, truss or indoor climbing wall, using the appropriate accessories.


Training exercises:

Set includes:

  • 2 Maxgrip Hybrids
  • 2 ropes
  • 2 length adjusters



Every single hold is completely machined and manually assembled in our workshop in Belgium!
