Answer 1

The words isometric and isotonic may sound confusing and complex, but as long as you can remember which is which, understanding the difference between them is actually quite simple. It's also important to know the difference between isometric and isotonic exercises and how they work because then you can incorporate them into your workout routine so you have a more diversified workout plan better suited for your needs.

Isometric

The easiest way to understand what isometric exercises are is to just think of them static, or still, exercises, because that's exactly what they are. When you perform an isometric exercise, you don't move or put your muscle(s) through any range of motion. You simply hold a pose for as long as you can. Examples would include: holding a static pushup position; holding a dumbbell in one hand mid bicep curl; or even pushing against an immovable object, such as a wall.

Isotonic

Isotonic exercises are the exact opposite of isometric exercises: You are moving and you are working your muscle(s) through a range of motion. Isometric exercises are actually the most common type of strength training exercises people do. For example, lifting weights, calisthenics, swimming, rock climbing, cycling: they're all isotonic movements.
