01

AI-generated workout plans

Short onboarding creates a training plan matched to goal, equipment, time and experience.

02

Guided workout session

The app guides users through exercises, sets and rest context instead of leaving them with a static list.

03

Progress and history

Workout logs, summaries and detail views help users see progress and return to the right context.

The challenge

Design a workout app that supports consistency, not only logging

FitSherpa needed to feel useful during the actual training session: quick enough to use between sets, structured enough to guide the plan, and stable enough to keep workout history meaningful over time.

  • Keep the workout flow simple under real gym conditions.
  • Connect exercises, logs, summaries, and progress into one coherent experience.
  • Leave room for new workout types and product iterations.

Original scope

What was actually delivered in this project

Mobile · Health & Fitness FitSherpa — your personal trainer in your pocket A mobile app that generates AI-powered workout plans, guides users through every set, and surfaces real progress over time — for people who want to train smart without paying for a personal trainer.

FitSherpa bridges both: a tailored plan generated from a 60-second onboarding, a guided session with set-by-set logging, and meaningful progress tracking over time. The challenge Build a product that, within a minute of opening the app, hands the user a personalized training plan — with no expert knowledge, no surveys, no manual configuration.

The plan has to be realistic for the user's constraints (time, equipment, goal) and evolve with their progress. The solution A cross-platform Flutter app backed by Supabase, with workout plans generated by AI through Edge Functions. Four-question onboarding, automatic plan generation, guided sessions with RPE/RIR, full lift & body history, full PL/EN localization, and Google & Apple sign-in.

Key features Everything a coach would tell you on day one Each feature answers a real user question: "How much should I lift today?", "What did I do last week?", "What if I don't have any equipment?". The modules below are those answers. AI-generated plans Onboarding captures hours per week, location, equipment and goal — AI picks the exercises, sets, and progression.

The plan is ready before the user leaves the onboarding flow. Guided workout sessions Step-by-step mode with exercise animations, inline rep and weight inputs, automatic saving, and RPE/RIR tracking for intentional intensity. Last-lift memory For every set we surface what the user lifted last time on this exercise — no more guessing whether "today is a weak day".

The delivered solution

A training experience built around active use

Workout continuity

The most important product decision was to treat a workout as a live process, not as a static form. That made routing, persistence, summaries, and detail views part of one experience.

The product was shaped around workout continuity: starting a session, tracking exercises, preserving progress, and returning to the right context without forcing the user through unnecessary screens.
