How do you build forearms with dumbbells?
How do you build forearms with dumbbells? Sit on a chair, bench, or box while holding a dumbbell in each hand. This time turn your arms over so your forearms face up and your palms are down. Raise your wrists towards your forearms, pausing for a few seconds then return to your starting position. Repeat for 4 sets of 10 reps.
