A fitness platform for where the Caribbean trains.
Lime is a coaching and gym-management platform built for individual Caribbean trainers and the gyms they work in. Locally rooted programming, regional payment rails, a Caribbean nutrition library, and three client archetypes — long-term members, seasonal clients, and tourists — designed in from the start.
Locally rooted, not localised.
The Caribbean nutrition library, beach and gully programming, and regional payment rails aren't translations of an American app — they're the spine of the product.
Three client lifecycles, one platform.
Long-term members, seasonal clients (Crop Over, new year), and tourists each have distinct onboarding, billing, and retention flows. The trainer experience handles all three from a single dashboard.
The trainer is the centre of gravity.
Trainers buy the platform; gyms come on as multi-trainer accounts. Marcus's reputation, content, and clients travel with him — Lime doesn't disintermediate the relationship.
The tourist arc closes back to the island.
A two-week visitor can become a remote subscriber, a returning seasonal client, and a referrer of group bookings. Each handoff is a designed moment, not a hope.

Aisha's trainer plan is the spine, but she can supplement on her own. Quick wins for a busy day, restorative work for the evening, something for the hotel room when it's raining.

A close, and an invitation.
Day 14. A small celebration, an honest note from her trainer, and the moment that turns a two-week tourist into a remote subscriber — or a returning seasonal client.
Two weeks, well lived.

Marcus's week.
Sessions booked, open slots visible, and one Caribbean-specific signal: how many tourists are looking at his sessions right now.
A new client, with context.
When Aisha books, Marcus doesn't just see a slot filling. He sees the tourist, her stay, what she's after, and what she's already told the platform.

What's intentional, what's placeholder.
A reader's guide for stakeholders. Where decisions have been made, where assumptions are flagged, and what's deferred to later iterations.
What this prototype is, and isn't
This is a designed walkthrough, not functioning software. Every screen is hand-built static markup intended to make the product tangible enough to react to. It exists to support partnership conversations (notably with Instafit246), gather feedback from trainers, and scope a build team. It is not a clickable app and the buttons do not do anything.
The current arc follows one persona — Aisha, a 14-day tourist from London — across both client mobile and trainer desktop. Long-term member and seasonal (Crop Over) flows are queued for a later iteration.
What's placeholder
- Pricing. The $35 BBD per session, $25 group rate, $45/month remote training, and $30–$40 BBD session range are illustrative. They have not been pressure-tested against local willingness-to-pay or trainer-margin math.
- The Caribbean food library content. Items mix Bajan (cou-cou, breadfruit, callaloo) and broader Caribbean (pelau, doubles). A production build would structure the library by island and region.
- The "142 Lime-curated workouts" figure. An invented number. The deeper question — how much content Lime curates itself vs. enabling trainers to publish into shared collections — is unresolved and worth a separate strategy conversation.
- The workouts themselves. No proprietary sequences from Instafit246's trainer are used. Workout names and structures are generic.
- The "Keep training from London" subscription. A strategically interesting model — turning tourists into remote subscribers — but the pricing, revenue split, and product depth are all open.
What's intentional
- Three client lifecycles, designed in from day one. Long-term, seasonal, tourist. The dashboard, billing, and retention flows differ per archetype. Tourist is shown here; the others are queued.
- Multi-currency from the start. Prices appear in $BBD; EC dollar, USD, and JMD would be handled at build time. Local payment rails are a differentiator, not a roadmap item.
- Trainer is the primary buyer. Gyms come on as multi-trainer accounts. Marcus's content and clients travel with him; Lime does not disintermediate the trainer–client relationship.
- The brand "lime." Drawn from Caribbean liming — gathering with your people. Reframes fitness away from gym-grind toward community and rhythm. "L!ME" with an inverted exclamation is held as a possible refinement if competitor collisions emerge.
- Editorial aesthetic. Fraunces (serif) for display, Manrope for body, warm sand background. Aspires closer to Cereal Magazine or Aesop than to a typical fitness app.
What's queued
- Crop Over 12-week seasonal arc. Date-targeted programming, pause/resume membership, the seasonal retention model.
- Gym-admin multi-trainer view. Closer to what Instafit246 would actually buy as an institutional customer.
- Long-term member dashboard. Body composition, strength PRs, and seasonal milestones rather than streaks and stay-day counters.
- Build team scoping. Team composition, cost ranges, and phased delivery plan. Held until the design direction is firmer.
