Fluid Precision
Turn brute force
into elegant speed.
Twenty-seven skills, a complete stroke and race-craft troubleshooter, and four weekly plans from beginner to elite — all derived from the biomechanical principles that separate competent swimmers from fast ones.
Minimize the water you disturb unless it's for propulsion.
The drill index
Fifteen stroke-specific drills, each tied to a biomechanical outcome. Filter by stroke or by what you're trying to fix.
Open water
Skills for swimming outside the pool — sighting, buoy turns, mass starts, and wetsuit body position. The environment changes more than the stroke.
Turns & starts
Every wall is free speed if you know what to do with it. Flip turns, streamlines, underwater dolphin kicks, and dive starts — broken down.
Stroke diagnostic
Tell us what your stroke is doing wrong. We'll tell you why it's slow, and how to fix it — with the exact drills to use.
Weekly training plans
Four seven-day programs spanning every level from recreational to elite. Every session ties back to a technical focus. Click any day to expand.
Swimmer's tools
A calculator for stroke efficiency, a progression for swimmers who struggle with breathing, and a glossary for all the jargon.
Distance per stroke measures how far you travel per arm pull — the purest test of efficiency. SWOLF (SWim + gOLF) combines strokes + seconds for a single length; lower is better. Track both over time, not against anyone else. Efficient swimming beats fast swimming at every level below elite.
Most breathing anxiety in swimming isn't caused by lack of oxygen — it's caused by holding air in. When you hold your breath, CO2 builds up, triggering the urge to panic even though you have plenty of oxygen left. The fix is a graduated progression: learn to exhale continuously first, add face-in-water comfort, then build up to rhythmic breathing during strokes. Don't skip steps. Each one takes as many sessions as it takes.
