Dryland Tip By Swimming World Correspondent G. John Mullen of SwimmingScience.net and CenterofOptimalRestoration.com

Purpose: Flutter jumps focus on foot speed directly following a squat jump. This is similar to kicks coming off the wall. Rapid foot speed is mandatory to perform multiple kicks, then re-position the feet before landing.

Directions: Stand with your feet shoulder feet apart, then squat down with your hips back and shins vertical. After the squat, explode off the floor then perform rapid flutter kicking. Resistance and 180 degrees of rotation can be added to make it more specific to a rotation following a flip turn. The exercise should be performed for short bursts, approximately 5 jumps.
