When performing various exercises such as pull-ups or Lat Pulldowns you may notice that your forearms fatigue before your target muscle does. Some gyms have grip strength machines or hand-held devices for squeezing. These exercises can be helpful if you need to open a jar or deliver a bone crushing handshake, however they don’t really help you develop the strength you need to perform other exercises. You don’t squeeze the Lat Pulldown bar in pulses. The issue is not grip strength, but rather forearm stamina.
Here is an exercise that will help you build forearm stamina: Get on a pull-up bar with an over handed grip. Get chin over the bar height, keeping elbows close to your torso and body relaxed and hang until your forearms give up. Work up to holding for 2 minutes. It is much harder than you think. This will give you enough forearm stamina to get through your sets and may even prove beneficial if you’re ever hanging off a building or cliff as so many Hollywood types so often find themselves.
