Stroke Lab — Swim360 Coach

The guaranteed way to fast track your tri, open water and pool swimming.

So you can swim 15-30 seconds per 100m faster and use 50% less energy — with the tools that diagnose your stroke, the sessions that build to your race, and me every week.

Then $67/month. Cancel anytime. No lock-in.

If you're reading this, you're probably still swimming three or four times a week and watching the clock refuse to move. Trying harder and somehow getting slower. Still coming out of the water behind people you out-run and out-ride every weekend. And whether the race in your calendar is a sprint tri, a 70.3, a full Ironman, or an open water mile, the swim leg is the one you're not looking forward to.

You know how I coach by now. Diagnosis first. Find the actual thing holding your stroke back, fix that, and the speed follows.

Stroke Lab is that approach as a weekly system. The tools that diagnose your specific stroke. The sessions built for your event. My weekly thread where you can ask me anything. Everything below is what's inside.

One thing worth knowing: Stroke Lab used to be $20 a week — about $87 a month. It's now $67 a month, and right now your first month is just $9. Try the whole system, send your check-ins, use every tool. If it's not for you, cancel before month two and you've risked the price of a coffee and a muffin.

How Stroke Lab works

This is not a video course.
It's a loop you run every week.

A course hands everyone the same videos in the same order — and most of them aren't about your problem. Stroke Lab works the other way around. It starts with what's actually wrong with your stroke, and only sends you to the things that fix it.

Find your real problem

Tell the Technique Dr what's happening in your stroke. It works out what to fix first — because working on the wrong thing is why the last two years didn't move the clock.

Get one focus and one drill

It points you to the matching problem video and the exact drill for your next session. One thing at a time — not fourteen cues fighting in your head at the wall.

Train it into your program

The Program Planner builds the fix into your sessions on the way to your race, or follow the three live sessions I post each week. Either way, you always know what to do at the pool.

Check in and repeat

A short weekly check-in updates your plan. Stuck on something? Ask me in the weekly thread. Then the loop runs again — that's how the clock keeps moving instead of stalling after week three.

That's why this beats a course. A course ends. The loop doesn't — it just keeps finding the next thing between you and a faster swim.

New this year

Two tools that adapt
to your swimming.

New

Program Planner

Tell it your event, your race date, your current pace, and how often you can swim. It builds your program from today to race day — then updates your sessions every week based on a short check-in.

This isn't a generic training app. Every session it writes comes from my session library — the same structures, progressions, and technique-speed balance I've used for 15 years to get adult swimmers faster. It's my programming, built to your race.

A real structure to your race, not a generic 12-week block
Sessions adjust each week to how you're actually going
No more guessing what to do when you get to the pool

New

Technique Dr

Describe what's happening in your stroke. It identifies the most likely cause, shows you the matching problem video, and gives you the drill to run in your next session. Built from 15 years of my coaching — the same cues and fixes I use with 1:1 swimmers.

One focus per session, so you're never overwhelmed
The exact drill for your specific problem
Available whenever you need it — before or after any swim

Also inside

The full system.

📚

Common Problems Library

Sinking legs, breathing panic, dropped elbow, timing. Your problem has a name and a fix.

🎬

Drill Library

Short, practical drills you can plug into any session. The drill, the cue, the focus. Done.

🏊

Live Weekly Sessions

Three new sessions every week, posted live. Swim them on your schedule, then compare notes in the comments if you feel like it — or just train and go. Zero planning on your part. The closest thing to a squad without the squad politics.

All My Courses

Freestyle Fast Track, 4 Step Fast Freestyle, and 14-Day Transformation. Already own one? You keep it — it all lives here now.

My weekly thread.
Ask me anything.

Every week I open a thread and answer member questions directly. Your stroke, your race plan, your training. Ask, get a real answer, get back in the water. Or stay quiet and learn from what others ask. This is the part no course can give you — a coach who actually replies.

Fair question — you've probably got a course or two gathering dust somewhere. Stroke Lab is built differently. The Program Planner refreshes your sessions every week, so there's always something current waiting. Three new live sessions land every week, and my weekly thread gives you a live reason to check in. And if it's genuinely not working for you, cancel in one click. No lock-in, no awkward email, no hoops.
