GripMaster

This my personal opinion I've put with my experience and knowledge in climbing. Take it as you wish. I'd also like to know what you think. Its not really for training strength. the only finger it could possibly help strengthen is my pinky 'cause i never use it. It's main function is injury prevention and recovery. To activate the muscles and tendons used in climbing more often so that a once a week Saturday or Wednesday night session doesn't come as such a shock for your tendons. That being said, this would only be the case if you were someone who didn't climb very often. If you're someone who climbs quite often, multiple days one even, GripMaster would be used more as a recovery tool. To flush forearms of unwanted lactic acid right after a session so that soreness and lack squeeze is lessoned (less effective than a proper cool-down. However, due to location an effective cool-down is not always possible, and thus we have GripMaster). It's best use is warm-up. If you're outside and unable to do a nice easy warm up traverse use GripMaster for 5 Min on each hand and the effects will be very similar. YOou still need to do a proper warm up! But GripMaster can help you along. 2/5 Because its marketed for what its worst at.

The Gripmaster is no substitute for actually climbing, but I've found that it helps with recovery. Maybe it's all in my head, but it seems that if I squeeze the Gripmaster on my drive home after a workout, my forearms feel looser the next day. (Squeezing lactic acid out, perhaps?) At any rate, it doesn't completely suck.

The spring action in mine started to stick after just a month. It is nice that they come in different difficulties. The individual finger action is nice as you can't cheat. There are some good exercises for your thumb too. It doesn't make you hands smell like rubber. I put mine in my bag and use it in the library, on the bus or walking to class. I haven't noticed a difference climbing though, to be honest.

Love the damn thing. Think they're down to about $9, or at least that's what Amazon says..

I got one of these about a year ago when I was going away on a long trip, except I got mine to keep my fingers in shape for guitar, and it worked pretty well. just like anything else, it's better if you climb (o rplay in my case) but it never hurts to use these when you're bored or just sitting around
