To be resistant to a swell or a current, swim with an angled body while leaning forward.

When you extend your arm in the water, lean forward and place your weight on your arm.

This movement is called edging, as if swimming through the water like a knife.

When you edge your body, it is important to tighten your core muscles and keep your legs together.

Practicing drills with an ankle strap helps to understand the feeling of this form.

Edging is the basic foundation of open water swimming.

You can balance on the edge of your body without kicking.
