Forearms and Grip Strength: How to Build Them Without Wasting Time

The bar slips on the deadlift while your back and legs still had more in them. On pull-ups, your fingers give out before your back does. In both cases the limit isn't the muscle you set out to train, it's your grip. Forearms are rarely anyone's priority, yet they decide a large share of every pulling exercise. Strengthening them takes very little time.

What grip strength actually covers

Grip isn't a single quality. It is usually split into three forms:

• Crushing grip: closing your hand around something, like a firm handshake or a hand gripper.
• Support grip: holding a load for a long time without letting go, as on deadlifts, rows or carrying heavy dumbbells.
• Pinch grip: squeezing an object between your thumb and fingers, like a plate held by its rim.

In the gym, support grip is almost always the one that fails: the target muscles could still move the weight, but your hand opens before the set is done.

What you already train without noticing

Every pulling exercise works the forearms: deadlifts, rows, pull-ups, lat pulldowns and shrugs. Hammer curls and reverse curls, with the bar held palms down, also hit the brachioradialis, the muscle on top of the forearm near the elbow. For many lifters that is enough to build a decent grip, especially in the first few years.

Direct work starts to pay off in three situations: your grip regularly gives out before the target muscles, you want bigger forearms, or you do something where grip matters, such as climbing or grappling sports.

The most useful exercises

Farmer's walk

A heavy dumbbell in each hand, arms by your sides, walk with short steps over a set distance. Keep your shoulders down and your torso upright, and put the weights down by bending your legs rather than rounding your back. It's the closest thing to what gives out on a deadlift. Progress by adding distance first, then weight.

Dead hang

Hang from a pull-up bar with straight arms, shoulders slightly pulled down rather than fully loose. The goal is to hold on as long as you can. Once 45 seconds feels easy, switch to alternating one-arm hangs, or hang a small weight from a dip belt.

Wrist curls

Forearms resting on a bench or your thighs, wrists over the edge, curl your wrist to lift the bar or dumbbell. Use the full range: let the weight drop at the bottom without letting go, then curl up without swinging. The reverse version, palms down, takes a much lighter weight because the wrist extensors are weaker.

Where to put them in your week

Always at the end of the session, never before heavy pulls: tired forearms would cut the weight you can hold on deadlifts or rows. Two exercises of two or three sets, at the end of two sessions a week, are enough for most people. Pair one support grip exercise, such as the farmer's walk or the dead hang, with one wrist curl.

Progress follows the same rules as everything else, the progressive overload principle: a few more seconds, a few more metres, then a little more weight.

Straps, chalk and mixed grip

Straps earn their place when grip is the limit on heavy sets meant for your back or legs. They're no problem as long as you keep them for those sets: do your warm-ups and first sets bare-handed, and bring the straps out when the weight calls for it. Our guide to lifting belts and straps covers how to use them.

Chalk soaks up sweat and improves your hold, if your gym allows it. A mixed grip on the deadlift, one palm facing you and the other facing away, stops the bar from rolling and holds better. It does create an imbalance, so if you use it, switch hands from one session to the next.

What we know about grip strength

Grip strength is heavily studied because it takes seconds to measure with a dynamometer. A large study of nearly 140,000 adults across 17 countries found that weaker grip was associated with higher mortality. That is an association: grip strength serves here as a marker of overall muscle strength, and the study does not show that training your grip specifically lowers that risk. The authors themselves say this still needs testing.

Build this work up gradually. If pain shows up on the inside or outside of the elbow, cut back on this work. Pain that lasts more than a few days, wakes you at night, comes with tingling or numbness in your fingers, or a sudden loss of strength in your hand are reasons to see a doctor. Our article on elbow pain has more guidance.

Frequently asked questions

Do forearms need their own training?

Not necessarily. Pulling exercises already work them hard. Direct work becomes useful if your grip gives out before the target muscles, or if you want bigger forearms.

Do straps stop you from building grip?

Not if you save them for your heaviest sets. Bare-handed warm-ups and first sets are enough to keep your grip in shape.

How long does it take to improve your grip?

Progress is often quick at first, partly because practice and technique matter a lot. Track your hang time or farmer's walk weight over several weeks rather than from one session to the next.

Grip is hard to judge by feel: a hang always seems long, even when it's improving. In Musku, the farmer's walk, wrist curls and the hand gripper are part of the exercise library, and you can create a custom exercise for dead hangs or anything else that isn't listed. A note on the exercise keeps track of whatever changes the difficulty, such as the distance covered or whether you used straps. The library, custom exercises and notes are all free.
