PROHANDS Gripmaster Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate & Exercise Each Finger

I play guitar as a hobby, not so much a passion, ever since a thumb injury left my thumb weak and caused me pain whenever I'd play. I had seen Gripmasters (or at least a knock-off brand) in my local guitar shop, but I always thought it was a kind of placebo - a "squeeze this, play 10x better!" too-good-to-be-true deal. But now, trying to think of some way to improve the strength of my thumb (and, to see if it would indeed improve my playing), I took a more serious look at the Gripmaster and bought one. Now that I've had it for a few days, I can already see that it's not just a placebo. While doing the exercises provided on the company's website (printed on the device), I can feel the individual muscles in my fingers and wrist working and flexing, and I think it's fair to say that if I stick with it, I'll be seeing results soon. It's a very convenient device as it obviously fits in your hand, so you can use it in class, while watching TV, on the job. But beware - the portability can make it very easy to want to drag it along and squeeze on it all day, overdoing it and possibly injuring yourself. This is no real fault of the product, though, but rather a warning from someone who quite definitely overdid it in eagerness the first day. It's hard to believe you can overdo something like this at a light tension, but the word "light" is a bit deceiving. I consider myself average in most respects, including my hands, and I was surprised at how much resistance this thing gives. Unless you already train your hands some other way, I would recommend starting with the light tension just to err on the side of safety. Five pounds may seem like nothing, but it can be a lot when it comes to the fingers. In closing, while I've only had the device a short period of time, I can tell by the way my hand responds to it that there is a lot of potential to improve my hands with it. It's small size makes it portable, but be careful not to wail on it all day long. Finally, unless you've already been training your hands, start off at light and go from there. All in all, the Gripmaster seems to be a handy (ha, a pun) little tool to improve the muscles in your hand, whether it be for strength training or for creating a better hand to play an instrument with.

Acheté suite à une récidive d'une compression du nerf ulnaire (la seconde opération est en attente). Souci de sensibilité et motilité des deux doigts externes ce qui se traduit par une paresthésie (fourmis), perte de sensibilité dans l'auriculaire et l'annulaire, et sur le bord interne de la main, une diminution de la force de serrage, fonte des muscles et des meilleures :( -cause inconnue - Je joue du piano, de la flûte traversière et cela handicape beaucoup. Depuis l'achat de cet appareil, l'exercice des doigts aussi régulièrement que possible redonnent une meilleure préhension en attendant. Autre remarque, il ne quitte presque plus ma poche ! Utilisé de l'autre main, la poigne se fait également meilleure, une bonne surprise quand l'on s'aperçoit que l'ouverture d'un bon pot de confiture devient complexe :) - et frustrant! - Solide (tombé souvent) et pas un accroc. Très bon matériel !

Bought this cause I had two problems. - My pinkies were really weak and often got locked in a hyperextended position due to breaking them when I was younger. - My grip strength for deadlifts was really weak, even for an overhand claw grip. SInce this lets you exercise each finger individually I am able to focus on strengthening my poor pinkies. I just leave it near my laptop on my desk and squeeze out a few sets 3 times a week. So far the results have been great. my deadlift strength is much better and no more annoying locked up pinkies. Will be moving to the next tension level soon.

Je vais essayer de vous donner mon avis le plus objectif possible. Très bon produit qui sent la qualité à plein nez! J’ai eu une rééducation de la main gauche pendant 1 an et j’avais besoin d’un produit pour remuscler ma main. Ce genre de produit peut être idéal pour des professionnels ayant besoin d’une grande puissance et contrôle sur chaque doigt. Le fait que chaque doigts a son propre mécanisme le rend parfait pour un trompettiste ou saxophoniste et autres... La prise en main est vraiment très bonne, et s’adapte parfaitement à une bonne prise pour forcer dessus. Je recommande vivement! Si mon commentaire vous à aider dans votre choix, n'hésitez pas à mettre un petit "j'aime"! ;) Merci d'avance.
