Bolt

Train smarter, not just harder

Bolt is an AI-powered fitness platform designed to make personal training feel personal, whether your coach is an algorithm or a real human. Instead of dropping users into a generic workout list, Bolt builds a guided experience: Onboard → Personalize → Train → Track → Improve.

The core of the app is built around active workout tracking: set-by-set logging of weight and reps, live rest timers, real-time coaching cues ("add 2.5kg to maintain progressive overload"), and session summaries that highlight volume, intensity, and calories burned. Every completed workout feeds into a broader progress system, personal bests, strength trends, and milestone badges like "100 Club" or "Power Surge", turning consistency into visible achievement.

The design challenge was to make dense workout data feel motivating rather than clinical. The final interface uses a clean light UI, bold typography for key numbers (volume, reps, PBs), card-based workout summaries, and encouraging micro-copy ("Crushed it, Alex! You outperformed 85% of your recent sessions") to keep users engaged set after set.

During AI Trainer onboarding, Bolt asks a few sharp questions, primary goal, training location, days available per week, and instantly generates a tailored plan, from high-intensity muscle-building splits to at-home mobility flows. Users can chat directly with "Bolt AI" to adjust their plan on the fly ("I have less time than usual"), and the coach responds with a revised, ready-to-follow schedule.

Bolt isn't just a workout logger. It's a training partner that adapts, pairing AI intelligence with the accountability of real coaching.
