Hand gripper
Grip trainer
A hand gripper fits in your palm, with two handles joined by a spring or flexible hinge. You squeeze the handles together and let them open again under control. It feels simple and focused, though the resistance can be surprisingly noticeable through your fingers, hands and forearms. Some models have padded handles or adjustable resistance for a more comfortable start.
You use it to practise gripping and controlled squeezing, helping you build hand and forearm strength for daily tasks and other exercise. It can support activities that involve holding dumbbells, carrying bags, opening jars or staying secure on climbing holds. Because the movement is small, you can also use it while seated, provided you keep your wrist in a comfortable, steady position.
It suits you if you want a compact, straightforward way to work on your grip, especially when larger equipment feels impractical. It takes very little storage space, and adjustable models let you begin with lighter resistance and increase it gradually. Start gently, since repeated squeezing can tire your hands quickly. A soft ball or rolled towel offers an accessible household alternative.
