Real interactions with Grit — program proposals, one-tap adjustments, post-workout reviews, missed-session check-ins, and the multi-sport weeks Grit actually builds.
Grit proposes your first program
A new user tells Grit they want to run their first half-marathon in 14 weeks. Grit asks a few questions about their schedule and recent runs, then drafts a complete, phased plan — and presents it as one editable card before anything is saved.
What Grit did
- Sized the block to 14 weeks across base, build, peak, and taper phases.
- Built in two strength sessions and weekly mobility, even though the user asked for a "running plan".
- Set training paces from the user's recent 5K time, not generic tables.
- Showed the whole program as an editable proposal — nothing saved until the user approved it.
A one-tap workout adjustment
After a tempo run, the user mentions it felt easy. Grit checks the recorded heart rate, agrees, and proposes bumping next week's threshold session — shown as a before/after card the user can apply in one tap.
What Grit did
- Cross-checked the user's note against the actual recorded HR zones.
- Proposed a +10s/km bump on the next threshold session only — not the whole plan.
- Rendered the change as a single before/after card with Apply or Discuss.
A review after every workout
The morning after a long run, Grit posts an automated review — effort score, splits, heart-rate zones, and how the session lined up with the plan — with quick replies to keep the conversation going.
What Grit did
- Pulled context from the user's program and saved preferences.
- Flagged a negative-split pacing pattern as a positive trend.
- Offered three quick-reply chips plus continue-in-chat.
A check-in when you miss a session
The user skips Tuesday's session. On Wednesday morning Grit checks in — no guilt-trip — with concrete options to get back on track.
What Grit did
- Detected the gap automatically at the scheduled review time.
- Sent a lockscreen notification that opens straight into the chat.
- Proposed three concrete reschedule options instead of just moving on.
A real multi-sport week
A marathon block, mid-build. The week Grit actually builds isn't all runs — it's runs, supporting strength, mobility, and genuine recovery, balanced so the hard days have room to land.
What Grit did
- Balanced load across modalities, not just running volume.
- Placed mobility right after the hardest session of the week.
- Left recovery days actually empty — no junk filler to pad the calendar.
Hands-free strength set detection
During a strength session with a paired heart-rate strap, Grit advances to the next set on its own when it sees your HR spike — no tapping the screen with chalky hands.
What Grit did
- Read live HR from a paired Bluetooth strap.
- Detected the recovery-to-effort transition and advanced the set automatically.
- Let the user override with a single tap when needed.
