The ones you can buy from sport shops are pretty useless for anything but warming up. If you mean business, go for the Captains of Crush by Ironmind but beware as they are seriously hard (the No. 1 is hard, No.2 extemely tough, No. 3 is near impossible for mortals and only 3 or 4 people in the world have closed the no.4). They certainly increase your pinch/general hand strength but don't do much for your finger strength. If you want to improve your finger strength, you time is much better invested in a good fingerboard routine (and sticking to it!) |
