The problem with conventional hand grippers is they are limited to a set poundage. You either have a hand gripper that is too light in resistance for you to make the gains you desire, or you have a hand gripper you can't even close. At last the problem is solved by the revolutionary John Brookfield Gripper! Unlike conventional grippers, JB Grippers have a wide range of resistance with every gripper. It's like having a whole collection of grippers in one. Simply put, it's like having a whole rack of dumbbells to workout with instead of being limited to just one dumbbell.
The new revolutionary JB Gripper has professionally-machined extensions fitted to every gripper. These extensions screw into the gripper the same way a silencer goes into a gun. The extensions change the leverage factor, which in turn changes the resistance.
There are seven JB Grippers ranging from the beginner's 50lbs to the strongman's 400lbs. Absolutely anyone can train and progress no matter what their strength level is. Whether you desire a stronger, firmer grip for sport or activity, or your goal is a firmer handshake to seal the deal, or even to develop the world's strongest hands. the JB Gripper will give you the results you desire.
With the unique JB Gripper you can do light warm up sets and move up to higher poundages, even to your maximum, then back to a cool-down set without even changing grippers.
You can train both hands at the same time and cut your workout time by half. Because of the revolutionary extensions, you can even work your upper body by  crushing the ends together. Imagine being able to train light, medium, and heavy all with the same gripper, and if that's not enough being able to train both hands at the same time, and even your upper body - all with one JB Gripper!
Because of the unique and revolutionary extensions on the JB Grippers, you are able to train with a wide range of poundages. The extensions create this because the leverage factor is changed by simply adjusting your hand on the gripper.
It is said that each JB Gripper is like having five grippers in one. Actually you have a much wider range of poundages than you can imagine. Each time you adjust and move your hand up or down the handle, the leverage changes as does the workload. By simply moving up the handle the width of your finger you make a substantial change in the workload. If you want to add just a slight amount of resistance you can move your hand just slightly to create this.
As you can see not only do you have five grippers in one, you have five grippers and everything in between. Instead of jumping 30, 40 or 50 lbs every time, you can jump 10lbs at a time with just one JB Gripper. It goes back to the saying,  with the JB Gripper you have a whole rack of dumbbells instead of being limited to just one dumbbell. We have solved the problem of conventional grippers.
Also because of the unique extensions you can do a wide variety of exercises never seen or thought of before with conventional hand grippers - training both hands at the same time, and even working your upper body - all with just one JB Gripper.
Anyone regardless of strength or age can train and progress to the results they wish to achieve by using just one JB Gripper.
The question is..."Who is going to be the first to close the 400 lb.
JB Gripper with one hand?" |
