Dumbbell Forearm Workout – Video and Tips

Dumbbell Forearm Workout – Video and Tips

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.

  • Set of dumbbells, we recommend buying a decent set of adjustable dumbbells.

    What a sick page this is. I like how you have provided anatomy and video examples to really emphasise your points and to back your information up. And the written instructions are easy to read for any level of learner. Very easy read. Great work, keep it up. I’ll be sure to visit your site now.

    Forearms are one of the most stubborn muscles in the body. Despite all the work I put in, they refuse to grow! These exercises look like they will help me.

    I do have some questions though. How do the upward and downward forearm workouts differ from one another? Do they target different muscles in the forearm? If you had to pick from both of them, which motion is most likely to improve the look of my forearms? I look forward to seeing your answers to these questions.

    Thank you for sharing and I hope you make it a great day!

      Hi Alax,

      Palms down exercises work the muscles at the front of the forearm, the extensor muscles. Palms up exercises work the back of the forearms the flexor muscles.

      Whilst its most important to work both the flexors and the extensors for mass and increased strength, the forearm flexors are the stronger and larger of the two sections, the flexors are also responsible for finger flexion, in simple terms “grip”. If you really only want to do one of the exercises, go for the palms up for increased mass and grip strength.

    I am very impressed with your article post on improving the forearms, you made if very understandable and the videos really helped me a lot.

    Does diet have anything to do with building your forearms, I have been thinking of trying a protein supplement do you recommend this or not?
