Pelaris is an AI fitness coaching app that builds periodized training programs for lifting, running, swimming, cycling and several other sports, then keeps revising them as real training data arrives. Instead of handing over a fixed template, it layers a plan from goals, chosen methodology, phases and weeks, down to individual sessions, and finishes with a consistency check so nothing in the program conflicts. Each phase, week and session carries a short rationale explaining why it is there. The product targets athletes who train for months and years rather than weeks, including people juggling several disciplines at once. A single program can combine, for example, marathon preparation, open water swimming and weekend football, with training load shifted around the key sessions. The library draws on 33 named methodologies, from Wendler 5/3/1 to Swim Smooth, and covers ten sport categories such as strength, triathlon, Hyrox, CrossFit and tennis. In practice, the user describes a goal in chat, reviews the proposed strategy and weekly schedule, and commits the program. During sessions the app tracks sets and reps live, adjusts weights from the previous session, flags personal records and updates estimated one-rep maxes. Check-ins on sleep, soreness and readiness can prompt the coach to propose swaps, such as replacing intervals with an easier steady run. Coach notes after each session explain what happened and what follows. Pelaris is available on the web, iOS and Android, and can also be reached from inside ChatGPT or Claude through the Model Context Protocol, with a stated 31 tools covering check-ins, workout logging and program changes. Workout sync lists Apple Health, Health Connect and Polar, while Strava sync is currently unavailable. Names, emails and locations are scrubbed before prompts reach the model, and data is stated not to be sold or shared. Among alternatives, it sits between simple workout loggers and human coaching services: tracking is free, while AI programs and the rolling coach are paid. It suits self-directed athletes who want structured, explained plans without a spreadsheet.
