Like a lot of other people, I had skinny forearms. After I bulked up by doing upper body exercises, my forearms were still skinny and weak. Making my upper arms bigger made my lower arms seem even smaller.
I exercised hard enough, long enough, and often enough to increase the size of my biceps, triceps, and a bunch of other muscles, but the exercises did not make my lower arm muscles significantly bigger or stronger. Nothing I did made a difference. It seemed like I was stuck with my thin forearms.
How to Get Bigger Forearms
You have muscles over most of your body. I got bigger broader shoulders while lifting weights. Doing push ups made my chest bigger. If you want to increase the size of your forearms then you should do exercises that target the muscles in your forearms.
Add finger and wrist exercises to your workout routine. Your hand and wrist contains tendons that are attached to muscles below the wrist. Tendons are like strings. You can't make the muscles in your wrist bigger, because there aren't any, but you can increase the size of the muscles between your wrist and your elbow.
Workout your fingers and wrists to make them stronger. If you work your muscles hard enough then you should feel the burn in your forearms. As your strength increases the muscles between your wrist and elbow will get bigger. Increase your strength over and over again to bulk up, until you have the results you want.
Dumbbell Wrist Workout
In an attempt to strengthen my forearm muscles and make the muscles bigger I did overhand front dumbbell raises, palm down wrist curls, palm up wrist curls, overhand dumbbell curls and hammer curls.
To do a front raise you raise the dumbbell in front of you while keeping your elbow slightly bent. Overhand means palms face down when your arm is parallel to the ground. A hammer curl is a variation of the dumbbell curl. The dumbbell is at your side with your palms facing in.
With these exercises I could not lift as much weight as I could doing exercises like bicep curls. When I started I had to use a lighter dumbbell. The objective was to increase my strength enough that I could lift significantly more weight and see how it changed the appearance of my arm.
Five days a week I went through my list and did the workout. The number of repetitions and sets was based on what I could handle on that day. I increased the weight when I could lift more while maintaining good form.
When working out your forearms keep the movement slow and steady.
Wrist Rolls and Push Up Variations
Wrist rolls are done by rolling up a rope with a weight attached to it. I tied one end of a rope around a dumbbell bar and the other around a weight. It works well. After rolling up the weight and rolling it back down a few times I could really feel it in my forearms.
The bar should be in front of you around shoulder height. Keep it close to your body. Your palms can face up or down. It would be a good idea to do it palms down half of the time. I added wrist rolls to my routine because they are a great lower arm exercise. They might be the best exercise for bigger forearms.
Try doing 5 to 12 reps per set. As your strength increases you can add more weight. Avoid hanging the weights over your feet in case the rope breaks or the knot comes undone.
Some push up variations target your forearms. I recommend decline, knuckle, finger or handstand push ups. Knuckle push ups will hurt if you don't do them on a soft surface like an exercise mat. You can make finger push ups easier by using your knees or doing them at an incline. I started on a set of stairs and switched to the floor when my fingers where stronger.

Forearm Workout Results
I wanted to bulk up because my lower arms were too skinny. While exercising my forearms became significantly stronger. I was able to increase the amount of weight I was lifting and the number of reps. When I felt my forearm I could tell it was firmer. When I looked at the forearm I noticed it was bigger in places.
It was easy to tell that my lower arms were stronger and firmer but the change in appearance was not as noticeable. I continued to work at increasing my forearm strength for a while longer and the change became more noticeable.
The forearm muscles are more like the triceps than the biceps. They don't get a lot bigger when you use them or flex them to show off. You can increase the size of your forearms muscles but you need to increase your strength and endurance a lot for them to get significantly bigger.
You may notice the line on my wrists. It is a tendon that is attached to muscle. The exercises did not change the size of my wrist or hands because they have tendons that are attached to muscles between the wrist and elbow.
If you want bigger forearms then add exercises like wrist rolls and finger push ups to your workout routine. Target the muscles between your wrist and your elbow by exercising your fingers and wrists.

Exercising your hands less can cause your forearms to become thinner. The arthritis and palm problem prevent you from exercising your hands enough so your forearms are thin. If you can try to exercise your hands more. A lack of exercise causes pain. Exercise can reduce joint pain. Strong muscles protect the joints.

My forearms have become thinner. I have some arthritis in both hands and also some genetic palm problem. Could this result in my forearms getting thin?
