A free 30-minute chat
Goals, history, what’s worked and what hasn’t. No sales pressure, we both decide if it’s a fit.
A real baseline
We assess 7 fundamental movement patterns together (online works beautifully) so your program starts exactly where you are, never where a template guesses.
Your program, in your own app
Guided sessions with weights pre-filled and rest timers running themselves. Miss a day? It moves. Machine taken? Swap it. Life happens, the plan bends.
A coach who actually watches
Every week is reviewed by me, personally. Progress when your numbers earn it, recovery when your body asks, and a direct message line in between.
Most people put off booking because they think they need to be ready. Here’s how unready you can be:
You talk
Tell me your goals in your own words, “more energy,” “a stronger back,” “hiking at 70,” or just “better.” That’s the entire preparation.
I listen, then map it
I’ll ask about your history, your week, what’s worked and what hasn’t, and connect it to what the science says matters most in your decade.
You leave with a plan
An honest read on your starting point and the two or three things worth doing first, yours to keep, whether or not we ever train together.
No workout. No weigh-in. No sales script. Camera on or off, your call.

No guilt, ever
Missed sessions are information, not failure. The app has no streak-shaming by design, showing up again is the win.
No cookie-cutter plans
Your schedule, your equipment, your energy, your cycle or life stage. The program bends around your life, never the reverse.
A human, not a bot
Every week reviewed by your coach. Every message answered by a person who knows your history. AI helps me; it never replaces me.
“Stronger,” “more energy,” “I don’t want to feel fragile”, that’s plenty. Naming it precisely is my job, and it’s the first thing we do in the free chat.
No. Women build strength readily but visible size very slowly, you’ll look leaner and more defined, not big. This is the most-asked and most thoroughly debunked fear in strength training.
The assessment is gentle movement, nothing to exhaustion, it’s the “before” photo, not a test you can fail. Programs start exactly where you are, including absolute beginner.
No. Programs are built around what you have, full gym, a pair of dumbbells, resistance bands, or just your bodyweight to start.
For most women, yes, and the data stays honest: every set you log feeds progress charts we both see, form gets checked live on video sessions, and we re-test your movement every couple of months. You’ll see the change in numbers, not vibes.
说！Coaching, the app guides, and all handouts are available in both English and 中文, whichever is more comfortable for you.
Worst case: you spend half an hour and walk away knowing your body better. That’s the worst case.

About me
I’m Celia Chen, an NSCA-certified personal trainer and a data scientist, based in the Bay Area. I coach women who want to feel strong now and stay capable for decades.
I built Coco because the two things that actually change a woman’s trajectory, progressive strength training and someone who genuinely pays attention, almost never come in one package. Here they do: evidence-led programming, a coach who reads your every session, and software that makes consistency the easy option.
As a data scientist, I care about what the research actually shows, not slogans, which is why every claim on this site traces to a source. As a coach, I care that the plan fits your real life: your schedule, your body, and your goals.

Strength is for every woman, at every age
Muscle and bone respond to training in your 30s, your 50s, and your 70s. It is never too early, and it is genuinely never too late.
Consistency beats intensity
The right dose, repeated, not punishment workouts. Every session is built to be finishable on a real-life day, so you actually keep showing up.
Honest about the evidence
I lead with the strong science and name the caveats. If a claim is shaky, I say so. That honesty is the whole point, not a disclaimer.
A human, not a bot
Every week is reviewed by me personally, and every message is answered by someone who knows your history. AI helps me; it never replaces me.
A growing library on strength training, explained honestly, the science, the decade-by-decade guides, and the deep dive for women.
The Science
Energy, sleep, brain, Alzheimer’s, and why we train heavy, graded honestly.
