Keeps your hands busy and strong.

This thing is a godsend at bouldering comps. While the organizers are blabbing about the rules and the scorecards and the tape colors, you're not just listening. You're cranking out a couple hundred reps on this little puppy. Then, when the clock starts and all them other fools head to the easy problems to warm up, you're way ahead of them. So you get the gnarly cave routes all to yourself before the crowds show up.

It works great, but your hands will get sweaty so use some chalk with it to prevent blisters on your fingers!

Love the gadget, great trainer. I wish it was a little stiffer.

I enjoy using this while sitting on the phone at work listening to someone blab and blab and blab... You get the idea. Like Gabe says, if you're wasting time at work, why not waste the time productively and build some strength in your forearms, hands and fingers.

Works well for beginners. I first bought this when I started out climbing. I definitely felt a burning in my arms and gave my hands something to do when I was itching to go out climbing. Overall I don't know how much this helped improve my forarm strength. I spend every other day climbing so now I don't use it at all because on the days off I need that time for my arms to recoup.

So I guess what Im saying is, it helps a little. Its cheap and couldn't hurt to get. So if you are thinking about it, then just get it. Its the price of a Burger King meal anyway you don't have that much to loose.

I dig the little blue ring, After couple of weeks and you start feeling a little like Popeye. After a couple of months you scouting around for a good anchor tatoo design. Not long after that you start craving spinach.
This thing is great for the car - How many reps can you do before you get to work? Also grat for meeting - How many reps before that guy in the cornflour blue tie quits talking?

This little trainer has helped me a ton. In the time since I got it I can notice a vast improvement in my climbing endurance, being able to hold on a lot longer. It keeps me occupied in times where I have nothing to do, or if I'm in an airport or class or where ever. It helps warm up my muscles on the way to the project, either during the drive or the approach.

A highertech version of the old hardman newspaper workout. Doesn't make your hand black, works your forearms.

BEST PURCHASE

This grip trainer is amazing. It is better than any spring resistance trainer as the rubber form fits to ones hand as they sqeez creating equal resistance across the entire surface. Pumping your arms before you know it.I had a knee injury from motocross and used it to keep up my forarm strength until i could start climbing again. When I barely got a brace an began training again i had a better grip than when i left, and could campus anything at our local climbing wall.

great little gizmo that helps keep fingers in shape for climbing, and helps build some forearm and grip strength. i keep one in the car, and i take it into the office when i remember to.. great little tool for when you're chatting on the phone, and otherwise wasting time doing work!!

indestructable chew toy!!!

This is my first forearm trainer and I like it. I noticed that it helped to keep my forearm strength when I couldn't make it out to climb.

After about two weeks of using the forearm trainer I did notice an increase in strength and endurance. However you get used to using the ring overtime and it doesn't quite have the same 'feel' to it as when I first started.

it's ok, but just a little bit too soft.

The Black Diamond forearm trainer has made a night and day difference in my grip on the wall. I used to have trouble crimping big round holds, but not anymore. Make sure you get proper instuction off the net so you don't dammage tendons.

This is actually only the weakest grip trainer in the whole set that is made by Black Diamond. I hope people will shop here at BackCountry for other things, but they don't have everything. Here's a site where you can actually get the entire set of three for only about $13.

Honestly this is not my favorite trainer, I feel it is too soft and prefer the independent fingers & variable tension of my Gripmaster. However, I do find this to be a great warmup tool.

I would still suggest the BD trainer to climber looking for Light to Intermediate tension...Also i'd say, great for guitar students!

These worked well, but the circle is rather big for small hands. It also lost a lot of it's rebound quickly.

This not only helps keep me occupied when driving or when i can not sit still, but it has really helped my climbing. I am not a really great climber and always struggled with my forearms burning out first! I got this to help out and I can now do the same climbs my forearms would die on and do them now with out burning out! I mix this up with the separate finger trainer. Make sure you rotate your wrist around, if you keep the same position all the time you will only work out one part of your fore arm, just play around you will feel it. I love how my forearm looks now, I can flex it and see the muscles. I can get lids of bottles with easy and I have just better grip all around. I have had people comment about my grip being strong for a girl now.

My friend got injured climbing and her wrist was hurt and could not climb and I got her one and it help her recovery.

I used this while on a month vacation and did not want to loose all my climbing strength. I came back with better grip than when i left!

Exercise anytime/anywhere. Very affordable. The dog will chew on this trainer if they get a hold of it! Works great.
