    Get stronger with the Black Diamond Forearm Trainer.

    Though Black Diamond's Forearm Trainer looks like a dog chew toy, it works surprisingly well at giving you a good forearm pump when you can't go climbing. Stash the Forearm Trainer in your desk at work or at home. Keep your arm strength up by squeezing it with each hand until you have good Coke bottle forearms, and you can barely type on your keyboard.

    Great for recovery

    • Familiarity: I've put it through the wringer

    My left arm had lost some grip following an injury, got this to put some work on it and it really helped. Now the only problem is keeping my kids from stealing it!

    Keep one at your desk!

      I got one of these to keep me from fidgeting too much during a long day at the office. Love it! You definitely need to use it for a while to feel that arm pump. It would be awesome if they made one that was slightly stiffer.

      5 dollar piece of rubber

      • Familiarity: I've put it through the wringer

      No suprises with this product- you get what you pay for. It's simple, durable, and you can take it anywhere. I do wish it had more resistance, but for 5 dollars it's hard to complain.

      It works

      • Familiarity: I've used it several times

      It's cheap and it will get you a good forearm pump. Perfect for the office. I've found that it helps to squeeze it on the hike in to a climb to have a little extra blood in the forearms before starting your climb.

      Lives in my car.

      • Familiarity: I've used it several times

      This guy lives in my car. I spend a lot of time on the road and therefore have plenty of time to work-out my forearms. I do recommend looking up forearm specific training programs for how to use a forearm/grip trainer as just aimlessly squeezing one of these isn't going to do what you hope for... except for maybe relieve stress.

      One thing to keep in mind, is always make sure to do oppositional workouts too.

      BD Forearm Trainer, take it everywhere

      • Familiarity: I've used it several times

      This thing is super simple, a small rubber donut that you squeeze. After using it for a few days it seems really durable, and I doubt it will lose its shape anytime soon (though it's cheap enough that if it does I'd buy another). I use it to keep up my hand strength for climbing, to remind me to use my rock rings when I'm home, and to motivate me to get up into the canyon. I bought 2, one for my house and one for my schoolbag (to daydream at the canyon out the window while my professor spews some nonsense about the weight load distribution of a metal oval ;). I could also see it being useful for loosening up hands after a long bike ride.

      Only reason I gave it 4 stars is because I'd like to see different resistance amounts, but this one is perfectly fine for all around use. I'm already coming up with new exercises like only using 2 fingers to squeeze it, using your thumb, quick and slow squeezes, holding the squeeze, etc. (I'm using it right now as I type, might be good for carpal tunnel? definitely gonna be useful after hours of video editing)

      • Familiarity: I've put it through the wringer

      I have one at work at my desk, and one at home. It's not a replacement for the gym, or time well spent on the rock. But it's a kind reminder of places I'd rather be, and it gets you warmed up.

      Give your mouse a break

      • Familiarity: I've put it through the wringer

      This wonderful device lives at my desk and does a fine job of keeping my hands & wrists limber throughout a typically numbing day at the keyboard.

      Will be a great addition to my non-beer hand, post biking to help unwind & relax the hands.


        I bought this item a while back and I think it's worth the money. The only reason I gave it four stars is because for me it makes my palm sore but it's not a big deal. I would definitely recommend this product.

        Train all day.

        • Familiarity: I've put it through the wringer

        Great little tool to keep those arms and your grip tip top when you're not hanging on your next problem.

        I keep one at work for in between typing; and one at home for when vegging out to movies.

        Train all day.

        Great for the price

        • Familiarity: I've put it through the wringer

        Great little thing to have while you sit at your desk or are stuck in traffic. Mine started to split on the inner edge after a few months and compromised the integrity of the ring. For the price it's not a big deal though. Get one!

        Good for Tattoos

          This thing's great to have at your desk. Do a hundred squeezes each hand a couple times a day. Hold shut for a minute a couple times a day, things like that.

          But, it's fantastic if getting tattoo work done. Tattoos hurt, it's nice to have this little guy to squeeze to refocus that pain and let it go.

          I bring it with me everywhere!

          • Familiarity: I've put it through the wringer

          This is an awesome little forearm trainer. I bring it with me everywhere. I bring it to work, in the car, at home. I use it all the time and no matter how often I use it, I still feel like its resistance is the same as the first time I used it, but I also feel stronger! I would totally recommend this to anyone looking for a simple and affordable forearm trainer.

          Love to use this on 4 hour drives

          • Familiarity: I've used it several times

          This thing is really awesome for long road trips and gets you really pumped if you use it for long enough! I think these things are great if you can't get to the gym and need a good hand/arm exercise.

          might help with bike-related hand pain

          • Familiarity: I've put it through the wringer

          I decided to try this because my hands had been killing me after long descents while mountain biking. There are all sorts of factors that contribute to hand pain based on your bike setup (handlebar setup, suspension, etc), in addition to what kind of trails you ride (rocky vs buffed out.) Instead of tweaking a bunch of things on my bike that may or may not have kept the numb hands at bay, I decided to invest in this lil' guy to see if strengthening my fingers/hands with it would help. After a few days of squeezing this in intervals while at my desk at work and a few days back on the bike, I definitely noticed an improvement in how my hands felt at the end of a ride. The hand numbness still comes and goes, but it's not as debilitating as it used to be. Definitely recommend it! To boot it's also been rolling around at the bottom of my purse for the two months that I've had it, when it hasn't been in use, and it still looks/feels as good as new.

          Comfortable but a little soft

          • Familiarity: I've put it through the wringer

          So this is a simple product. Grab a big rubber donut and squeeze. That's about all there is too it. I'm very new to climbing, but even with my relatively low grip strength I found this product to be a little soft. It's still good for training your grip strength, but I feel like it'll be pretty easy to max the product out in terms of just how much strength it can help you build.

          Be careful not to do it too much. Took the little donut to a move and squeezed on it for a couple hours and worked up a couple of blisters on my fingers. Still a very comfy device, but I overdid it.

          I saw on the other site given by Matthew...

          I saw on the other site given by Matthew the resistance weight on the three in the set but they are all different colors. Does anyone know about what it is for this blue one? or at how hard it is?

          Joey, The blue is the middle resistance. I can't remember the resistance, but I want to say somwhere around 7lbs. It is fairly stiff, while providing rather "light" resistance it will work your forarms and fingers.

          Joey, I have the blue one and it has about 10-15lbs of resistance. I'd recommend more resistance if you climb very much. I'm new to the sport but have already gone to using my "blue" forearm trainer for several hours before my forearms get tired...hope that helps
