Forearm strength is the quiet limiting factor behind almost every pulling exercise you do; deadlifts, rows, and pull-ups all eventually get capped by how long your grip can hold on, not by how strong your back actually is. The forearms handle two main jobs, flexing the wrist and gripping, and both benefit from direct training rather than relying entirely on carryover from other lifts. Wrist curls and reverse wrist curls train flexion and extension directly, farmer's carries build raw grip endurance under load, and reverse curls hit the muscles on top of the forearm that most routines never touch. Work in a higher rep range here, 12 to 20 reps, since forearm muscle fibers respond well to volume and recover quickly between sessions. Two to three times a week is reasonable, and forearms are forgiving enough to train more frequently than most muscle groups without much risk of overtraining. The most common mistake is relying entirely on other lifts for grip training and never doing anything direct, which leaves grip as the first thing to fail on a heavy deadlift or a long set of pull-ups. A second is using wrist straps on every single pulling exercise, which removes the grip demand entirely and stalls forearm development over time. A third is ignoring extension work, training only the flexors and creating an imbalance that can contribute to elbow pain, similar to what shows up in tennis elbow. Dumbbells and barbells cover wrist curls well, and a simple pair of farmer's handles or heavy dumbbells covers the carry work.
