Why Use A Grip Developer

Grip developers have often been seen as a gimmicky play exercise device that doesn’t really do much good. The truth is quite different and, quite frankly, it’s about time that this compact exercise machine started getting some respect.

Here are four reasons why you need include grip training into your routine:

  • They will develop hugely impressive forearms. The forearm flexors and extensors control the opening and closing of your fingers, which is the very action that a grip developer works on.
  • They will dramatically increase your hand endurance. This will allow you to apply force for a longer period of time. You’ll also be able to carry heavy objects for longer periods of time.
  • You will have far greater hand strength. This will allow you to hold a barbell for longer when doing exercises like the deadlift and to keep going longer on moves like chin ups.
  • You will improve in your dexterity. This means that your individual fingers will each be stronger. If you do things like typing or playing a musical instrument, you will know how important that is.

Contrary to what people believe, general strength training does not usually transfer over to grip strength. Doing a lot of deadlifts or barbell curls is not going to give you a mega powerful grip. It will require specific grip training to achieve that. And to achieve that you will need to invest in a quality grip developer.

Summary

Your hand gripping strength is the vital link between your body and external forces that you are required to lift. Developing it should be a prime concern.

When you’re ready to get serious about your grip training, look out for the The Project Crush gripper from Caliber Fitness. Here’s why

It was the most impressive grip strengthener we came across. . .

  • It’s traditional, old school design provides the robust strength and spring quality that you need to consistently improve your gripping ability.
  • The downloadable e-book will provide you with a wide variety of workout options to keep your body guessing.
  • The knurled handle option simulates the conditions that your hands encounter down at the gym.

For those reasons, it crushes the opposition.

Learning how to improve your grip means stepping into the world of grip strengtheners. We’re all familiar with the over sized spring type grippers that we used to play with when we were kids. Well, all these years later, the spring gripper is still around.

The spring grip has stood the test of time because it works. There are a range of newer, more techno looking grip developers on the market today, too. Many of them are nothing more than mere toys, lacking the grip resistance to be of any use to serious trainers. But there a few standouts that definitely deserve your consideration.
