Adaptive Training Plans

Most training plans are PDFs. A coach (or a template) wrote them once, you printed them out, and from week four onward they have nothing to do with how you actually feel. You slept badly on Tuesday, the Wednesday intervals crushed you, you skipped Friday, you've been eating 500 kcal under target all week, and now you're staring at Saturday's long run wondering whether to do it as written or back off. The plan can't help you. It's paper.

An adaptive training plan reads your data, your life, and the rest of what you're doing in the app every week, and rewrites itself before you start the next block. Movement Rebels works this way by default — every Sunday the coach generates a fresh week based on what actually happened during the last one, across every discipline you train.

What gets adapted, and what doesn't

Adaptation isn't randomness. The coach holds your goal (5K PR, first half-marathon, body recomp, hybrid build, Hyrox prep) and the periodization model (block, conjugate, linear) constant. What flexes:

• Volume. If HRV is down off baseline, you missed two sessions, or Rebel Fuel shows you've been 600 kcal under target three days running, next week's volume drops 15–25%. You don't lose fitness in a single week. You lose it by stacking weeks of unrecovered + underfueled work.
• Intensity placement. Hard days move based on which days you actually have time + are recovered for. A threshold session prescribed for Tuesday gets shifted to Thursday if Tuesday's morning brief says you're not ready.
• Session swaps. Long run swapped for a brick if you have a race in three weeks. Strength deload week dropped in early because the bench numbers stalled two sessions in a row.
• Cross-discipline balance. If your strength volume jumped 30% last week (because the program said to), endurance intensity drops to compensate — concurrent training only works when total stress is managed.
• Deload timing. Most templates schedule deloads every 4th week. Your body doesn't read the calendar. The coach watches readiness signals across HRV, RHR, sleep, mood check-ins, fueling, AND performance trend, and schedules the deload when you actually need it.

What stays locked: your goal, the macrocycle, the key sessions (race-specific work, strength PR attempts). Adaptation serves the goal — it doesn't replace it.

The weekly loop

Sunday night, the coach generates next week's plan. Before it writes a single session, it reads:

• The last 14 days from Garmin / Apple Health / Strava. HRV trend, sleep score average, RHR drift, training load, completed sessions, perceived efforts.
• Your strength log inside MR. Sets, reps, RPE, missed lifts, PRs — the coach reads them the same way it reads endurance data.
• Rebel Fuel. Calorie balance, protein intake, hydration. If you've been hammering threshold work on a 500 kcal deficit, the coach knows why your numbers are off.
• Recovery tools used. Breathwork, NSDR, cold exposure, fasting timer — all logged in the same app, all factored in.
• Your athleteMemory. A persistent profile the coach has been building from every chat — injuries, preferences, what worked, what didn't, what's coming up in your life next week.
• Your goal + timeline. Race date, target lift, body comp goal, whatever you signed up for.

Then it writes the week. You wake up Monday to a weekly brief: "Last week you hit 3 of 4 sessions, HRV trended down 6%, protein averaged 1.2 g/kg (low) — this week we drop volume 20%, keep the Saturday long run, swap Tuesday threshold for Z2, bump protein target to 1.8 g/kg." Each day's session is in the calendar with a tap-to-open card.

Mid-week, if something changes — bad sleep, a tweak, an unexpected travel day — you tell the coach in chat and the rest of the week re-plans. No new credit charge.

What this needs to work

Adaptive only works if the coach has data. Four streams matter:

1. A wearable. Garmin (live), Apple Health via HealthKit in the iOS app (live — and that's how WHOOP, Oura, and Polar data reaches the coach today, since all of them push to Apple Health), Strava (live for read + write). Without recovery signals, "adaptive" is just guessing.
2. What you log in the app. Strength sessions, Rebel Fuel meals, recovery tools used (breathwork, NSDR, cold, fasting), body comp check-ins. Everything inside MR feeds the same coach — no separate apps to bridge.
3. A conversation history. The coach builds athleteMemory across every chat. Skip the chat and the coach knows less about you than a clipboard.
4. A clear goal. "Get fitter" doesn't program. "Sub-1:40 half on October 12" does.

Set those up and the loop runs itself.

How Movement Rebels handles this

The whole product is built around the adaptive loop. Default flow:

1. Onboarding captures your goal, training history, available days/hours, equipment, disciplines (strength, endurance, hybrid).
2. First plan generates as soon as onboarding completes — written from your inputs + the coach KB.
3. Wearable sync kicks in within a few hours of connecting (Garmin / Apple Health / Strava all backfill 90 days of history).
4. Daily logging happens in the same app. Strength sets, Rebel Fuel meals, recovery tools, body weight, biohacks — every entry feeds the next plan-gen.
5. Sunday weekly brief runs automatically — no clicking "generate". A new week lands every Sunday based on the last one.
6. Daily morning brief at the time you choose. Quick read of last night's recovery + the day's session + any flags.
7. Chat anytime. Skip a session, get a cold, swap days, ask why threshold is on Thursday — the coach replies in seconds and the plan updates if it should.

Unlike Garmin Coach (canned endurance only), Strava's free plans (canned, no recovery read), or Hevy's lift-only logging (no plan, no AI), every layer of MR's adaptive loop is reading current data from every discipline you train. Nothing is canned. Nothing is isolated to a single domain.

Pricing + access

Adaptive plans are not gated behind a tier. The 7-day free trial includes full coach access AND full Rebel Fuel AND full strength logger AND every recovery tool — plan-gen, weekly brief, daily brief, chat, post-workout debriefs. After the trial, Pro+ at $20/month keeps everything running, including unlimited plan regenerations.
