The Best Forearm Exercises for Size and Strength

Not all forearm exercises are created equal. Some build mass. Some build endurance. Some prevent injuries that would otherwise sideline you for months. This is the definitive ranked list — with the sets, reps, and form cues that actually make them work.

How to Read This List

Each exercise below is rated on three dimensions: Mass Potential (how much it contributes to forearm size), Strength Transfer (how much it improves performance in compound lifts), and Injury Prevention (how much it reduces forearm and elbow injury risk). Use this to build a balanced programme.

The Tier 1 Exercises — Do These Every Week

1. Thick-Bar Training (Fat Grips)

The highest-efficiency forearm stimulus available. By wrapping any bar in fat grips, you increase the grip diameter to 2.25 inches — the optimal thickness for maximum forearm recruitment. Every exercise you already do becomes significantly harder on the forearms without changing your programme at all.

Best applied to: Deadlifts, rows, curls, pull-ups, farmer carries

Protocol: Use on 2–3 exercises per session. No additional forearm volume needed on thick-bar training days.

2. Forearm Roller

The single best direct forearm mass builder. A weighted roller on a rope targets wrist flexors (forward rolling) and extensors (reverse rolling) through a long range of motion under constant tension. No other exercise provides this stimulus.

Protocol: 3 sets forward, 3 sets reverse. Start at 5–10 lbs. Build weekly. Stop before form breaks down.

3. Dead Hang

Hang from a pull-up bar with straight arms. Simple, brutal, effective. Builds crushing grip endurance that transfers directly to deadlifts, rows, and any pulling movement. The longer you hang, the better your grip becomes at everything else.

Protocol: 3–5 sets. Start with 20-second holds. Build to 60+ seconds. Use a pronated (overhand) grip.

4. Farmer's Carry

Pick up heavy dumbbells and walk. One of the highest-stress forearm exercises in existence — the combination of high load, walking instability, and time under tension creates a stimulus the forearms can't ignore.

Protocol: 3–4 sets of 30–50 metres. Use a weight you can walk with proper posture. Progress load weekly.

"The farmer's carry is the most functional forearm exercise. It trains strength, endurance, and stability simultaneously under real-world loading conditions."

The Tier 2 Exercises — Rotate These In

Zottman Curl

Curl up with a supinated (palms up) grip, rotate to pronated (palms down) at the top, lower with palms down. You get bicep work on the way up and brachioradialis loading on the way down. Two exercises in one movement.

Protocol: 3 × 10–12. Controlled on the lowering phase.

Reverse Curl

A standard barbell curl with palms facing down throughout. Directly targets the brachioradialis and wrist extensors — the most underdeveloped forearm muscles in most athletes. Also protects against lateral epicondylitis (tennis elbow).

Protocol: 3 × 12–15. Use about 60% of the weight you'd use for a regular curl.

Reverse Wrist Curl

Forearms on a bench, palms down, curl the wrists upward against a dumbbell or barbell. This directly trains the extensor group — the most important exercise for preventing wrist and elbow injuries in any athlete who trains regularly.

Protocol: 3 × 15–20. Light weight, full range of motion.
