Isometric Exercises: What They Are, Benefits, and How to Get Started

Isometric exercises might sound complicated, but they’re as simple as holding a position without moving.

Think of it like trying to push a wall—you’re engaging your muscles even though there’s no actual movement.

So, why should you care? Isometric exercises are awesome for building muscle endurance and strength without putting extra strain on your joints. They’re also a great way to target stubborn muscles that are hard to activate with dynamic movements. Plus, you can do them almost anywhere—no fancy gym equipment is required!

Getting started is easy: Simply pick a few exercises, hold each position for a set amount of time, and gradually increase your hold as you get stronger.
