Make your forearms bigger..
Shit don't wanna grow no matter how hard... I work out.
Must be genetics.

Get fat grips when training back / biceps
Train forearms directly
Lift heavy stuff

Repeat

Will farmers walks with 50lb dumbs get the job done?

.....50? Are you like 100lbs?

Have to start somewhere so yes

youre saying i should hold 100lbs in both arms?

It should be progressive, so if 50 is heavy for you than thats fine. But if you're worried about forearm size and 50 lb farmers are a struggle, its not because they're not growing, its because you're smol.

Keep lifting, they'll grow.

What does your current routine look like?

I'm just starting out again. Haven't really put one into works. I usually cycle, push-ups and pull ups, triceps dips, some sit ups, squats and dumb bell curl and or declines.

You're just starting again but your forearms wont grow no matter how hard you work.

There's some inconsistencies here.

Do you compounds, do your rows, do some weighted chin ups.
