    Hand grips are compact and portable lever-type devices that you squeeze in order to build up arm strength and muscle. Athletes mainly use them to increase their ability to excel at their chosen sport. Most sports involve the concept of moving weights or transferring the power of your body through the hands. Hand grips allow you to build up your lower arms, and this works to make you a better athlete, whether your sport is football, martial arts, weightlifting, baseball or even golf. Many of these sports depend on high lower arm strength, and working out with hand grips helps you develop this strength.


    1. More Forearm Muscularity

    If you have ever wanted forearms that look impressive and bigger than most other men, you should work out with hand grips. The principle works in this fashion. Muscles that are situated in your forearms are the ones controlling your fingers. Your forearm flexors control the closing of your hand, while your forearm extensors control the opening. These muscles will be the primary beneficiaries of using hand grips.

    1. Hand Endurance

    As you work with hand grips, you can train yourself to apply pressure for longer periods of time. A practical area for which this provides instant benefits is, for instance, when you are carrying things like suitcases or heavy bags.

    1. Increased Hand Strength

    The third benefit of hand grips is increased hand strength, where you train to increase the power of both your fingers and your wrists. Increased hand strength will help you out in areas like the gym, where you can then hold on to weights for longer periods of time.

    How to Exercise With Spring Hand Grips

    A stronger grip can benefit athletes of every skill level -- from weekend warrior to professional. Many strength and conditioning programs include wrist exercises, but exercises that specifically target the gripping muscles of the hand and forearm are often overlooked. Mechanical hand grips -- essentially stout springs with handles on them -- are inexpensive training devices that isolate the muscles important to grip strength. Work in several sets of exercises with hand grips during your regular upper-body training to quickly tone and strengthen your fingers, wrists and forearms.

    Step 1

    Place one handle of the spring hand grip against your palm to begin a squeeze-and-release exercise. Wrap your fingers around the other handle. Squeeze the handles together as far as you can. Hold the closed position for 5 seconds, then slowly release your grip. Start with two sets of 10 squeezes for each hand, then build up over several weeks to four sets.

    Step 2

    Grip a hand grip between the palm and fingers of one hand, as far toward the tips of you fingers as possible, to prepare to do a reverse squeeze exercise. Close the grip using both hands. Pull your "helper" hand away, and release the grip as slowly as you can. Start with two sets of five reverse squeezes with each hand, then build up to four sets as you get stronger.

    Step 3

    Place the hand grip against the palm of you hand, then place the tips of your fingers on the finger springs or "buttons." Curl your fingers toward your palm to close the springs, then slowly release your grip. Add difficulty to this exercise by curling in only one finger at a time. Start with just one set of 10 finger curls on each hand, then work your way up to three or four sets.


    Squeezing exercises build strength in the large muscles of your forearms with basic squeezing exercises. The brachioradialis and carpal flexor muscles generate a large proportion of your grip strength. Most wrist and grip exercises work these muscles to an extent, but you can focus on them by doing the squeeze-and-release exercise in Step 1.

    Reverse-squeeze exercises improve your hand and forearm extensor muscles. Carpal extensor muscles are difficult to isolate, unless you invest in some fairly pricey, purpose-built commercial devices. Use a hand grip rated one strength level higher than you normally use for squeezing exercises
