Popeye's legendary forearms are often associated with his superhuman strength after consuming spinach. While real-life bodybuilding might not give you cartoon-like proportions, you can certainly build strong, well-defined forearms through consistent training. Here are some exercises that can help:

1. **Wrist Curls:** Use a barbell or dumbbells for wrist curls. Sit on a bench, rest your forearms on your thighs, and curl your wrists up and down.

2. **Reverse Wrist Curls:** Similar to wrist curls but in the opposite direction, working the muscles on the top of your forearms.

3. **Dead Hangs:** Hang from a pull-up bar for time. This engages your grip and forearms to support your body weight.

4. **Farmer’s Walk:** Hold heavy weights (dumbbells or kettlebells) in each hand and walk for a distance. This not only strengthens your forearms but also works on your grip strength.

5. **Plate Pinch:** Hold weight plates between your fingers and thumb, then lift and hold for a period of time.

6. **Hammer Curls:** Perform curls with dumbbells in a hammer grip (palms facing each other).

7. **Grip Strengtheners:** Use grip strengtheners or hand grippers to target forearm muscles.

Remember, consistency is key. Gradually increase the weight and intensity as your strength improves, and allow adequate rest for recovery. And of course, while these exercises can build strength and muscle, genetics play a role in how muscles develop, so results may vary from person to person.
