Three mornings, three answers
“I can hold your plan today.”
Standard volume. Nothing dramatic—just the work.
Your plan shouldn’t break the first time life gets busy.
Static plans assume your week looks like it did when you wrote them. Yours doesn’t.
Then Thursday happens: meetings run late, five hours of sleep, 20 free minutes.
Static plan
The program still expects “Day 4”. One miss and you’re behind — the rest of the week quietly unravels.
Dorsi
Thursday shrinks to the 20-minute version — still done. Friday never notices.
Still on trackThe promise
Just show up.
You bring the minutes. Dorsi handles the decisions — what to lift, how much, and when to back off. No streaks to protect. No Day 1 to dread.
The system
A coach, not a tracker.
No streaks. No reminders. No guilt. Just decisions, four layers deep. See how the personalized workout plan stays connected.
Decision layer
Open the app and you have one answer: do this today. Tap “Why?” to see what data drove it.
AI Briefing
HRV dropped 12 points from baseline. Sleep was 5h. Lighter today, real volume Thursday.
Why?
Adaptive layer
Rough day or 20 minutes? Lower sets, lighter loads, shorter version — same intent.
Live layer
Rest extends when you need recovery. Screen tints when your heart rate runs high.
Continuity layer
Back from travel, off for months, sixth Day 1 — the plan picks up where your body is, not where it “should” be.

Tell it. It listens.
Skip a day. Swap a move. Tell it how you feel. Plans adjust in real time.
When time disappears
Built Apple Watch–first, not phone-first.
The whole session, on the wrist.
Heart rate, HRV, sleep — all live where the training happens. Open the watch and you’re in your first set within 30 seconds. Read how we assess Apple Watch HRV accuracy.
Logged there. Reviewed here.
The session lands on both devices the moment you finish — nothing to plug in, nothing to sync. iPhone is for review. Garmin and others are on the roadmap.
It fits the day you actually have.
It’s 6:47 am.
You slept 7 hours. HRV is balanced. Today’s plan was waiting before your coffee was poured.
You said “only 20 minutes.”
Type into chat. The plan rewrites. Open your wrist.
Tuesday. You’re toast.
HRV dropped. Sleep was rough. Dorsi already knows — today is shorter, lighter, and ends in mobility. Explore the science behind adaptive training.
It remembers you.
The more you train, the better the plan fits.
12 weeks in. Knows your shoulder. Knows you train Wed at 6:30. Knows your bench has gone up 12 pounds.
Who it’s for
If any of this sounds like you.
On your sixth Day 1.
Tried, broke, restarted. You need a coach that doesn’t make you start over.
You lost the weight. Now what?
Recomp, build, or something else — Dorsi redefines the goal and gives you a way in.
45 hit different.
For keeping up with the kids, staying functional, not getting hurt. Starts from where your body is.
When am I meant to do strength work?
Runners, cyclists, climbers, fighters — strength as a tool, not the point.
And who it isn’t for.
You program your own training and chase PRs.
You’d fight the coach. Pick a tool built for lifters.
You want gram-perfect macro logging.
That’s a nutrition app’s job. Dorsi talks food through a training lens — fuel, recovery, what tonight’s session needs.
You train for pace and mileage.
Go endurance-first. Dorsi is strength-first, cardio as support.
Common questions.
Today’s session, decided for you.
