Water running gets a bad rap as aqua aerobics by a different name. But with proper technique, it makes for a tough workout and is a perfect training tool if you’re injured or need variety. You’re working with high resistance (think about it: water is thicker than air) without any pounding on your joints.
“If you’re injured from running, swimming won’t quite give you that fix,” says Robert Valentin, a New York City-based Deep Water Running coach for 15 years. “If your form is right, you’ll feel like you went running afterward.”
Valentin adapted his technique from his mentor, the late Doug Stern. By working with your leg almost straight and toes pointed, you can gain the most resistance from the water.
