Are your forearms the weakest looking part of your arms, do you suffer from a weak grip? If you do then this dumbbell forearm workout is for you!

Training hard on biceps and triceps only to have skinny forearms ruins the overall look of the arms, targeting the forearms with a couple of extra isolation exercises will help give you thicker, fuller forearms.
Our dumbbell forearm workout is a quick and simple workout that will blast your forearms, make sure you do the exercises properly using the correct form, watch the vid’s and read the exercise tips!

Forearm Exercises Increase Grip

Increased grip will help you with many other exercises in your routine including rows and deadlifts, having a stronger grip and forearms will give your shoulder and bench press a boost too.A heavyweight training routine will help build your forearms, heavy pressing and pulling involves a lot of forearm work and some guys will forgo doing any isolation work on forearms feeling they get enough from their routine as it is.But if you feel your grip weakness is stopping you pushing yourself further with movements like the bench press or deadlifts, then some isolation forearm exercises will really help you out. Not only will your strength increase, your forearms will look bigger and more impressive.

Anatomy of The Forearm

The forearms can be divided up into two groups, flexors, outside of your forearm (anterior) and the inside of the forearms extensors (posterior). You can see this in our diagram.
There’s nothing complicated about it, think of it this way “one set of muscles flexes the wrist and fingers and pronates the arm and the other set extends them and supernates the arm”  says Mike Matthews best-selling health and fitness author.Both the flexors and the extensors are divided up into deeper sublayer groups but for our workout, all you need to know is we will be working both of the main muscle groups, flexors and extensors.
