Serious endurance training should not require renting your own training history back by the month. OpenAthlete plans your season as blocks, weeks, and sessions, with A, B, and C races marked and illness or travel periods that move the sessions they cover. You build structured workouts from your own zones, pace, power, heart rate, or percentages of VMA and FTP, save them to a reusable library, and send them straight to Garmin, COROS, and Suunto watches at the next sync. Completed activities arrive from Garmin, COROS, Suunto, Polar, and Strava, or as FIT, GPX, and TCX files, and each interval is graded against what was planned. Analysis covers detected climbs, time in zones, aerobic decoupling, gradient-adjusted pace, and weather, with non-destructive fixes for heart-rate spikes. Progress views track records by distance and duration, critical speed and power, and fitness, fatigue, and form projected over your upcoming sessions, alongside HRV, resting heart rate, and sleep from your watch. Coaches see compliance, volume, and form for every athlete on one screen, get alerts for reported pain or inactivity, and exchange comments and real-time chat with athletes. A calendar feed keeps Google, Apple, and Outlook in step, and the web app installs on your phone home screen.

Coach Watts is a self-hosted AI endurance coach that reads your training, recovery, sleep, and nutrition data together and tells you, each day, whether to push or rest. Connect Intervals.icu, Strava, Whoop, Oura, Garmin, Withings, Wahoo, Polar, Fitbit, Hevy, Yazio, Rouvy, or Ultrahuman and every workout, HRV reading, sleep score, and meal lands in one athlete profile instead of fourteen separate apps. Each session gets a detailed breakdown with an execution score, and the performance view tracks Fitness, Fatigue, and Form alongside power curves so you can see a training block working, or quietly burying you. Daily recommendations weigh HRV and sleep before suggesting intensity, and the interactive chat answers questions against your own data when you want the reasoning behind a call. Adaptive plans generate around your schedule and goals, then adjust as life interferes. Nutrition tracking applies metabolic fueling logic that shifts between Eco, Steady, and Performance modes based on session intensity, so long rides get fed differently from recovery spins. Coaching alerts and system messages arrive in the dashboard, Telegram coaching is available for nudges on the move, and the whole platform speaks more than ten languages with timezone handling that follows traveling athletes. A Google account provides sign-in and the Gemini models behind the analysis, while your synced history stays in your own database.

LiftTrace is a self-hosted weightlifting tracker that keeps your entire training history, programs, personal records, and progress photos on your own server in a single Docker container. Log every set with weight, reps, RPE, warm-up markers, and supersets, or type a line like bench 3x5 at 225 and let the Smart Log parser turn plain text or a voice note into structured sets. Follow multi-week programs where each week prescribes its own sets, reps, tempo, rest, and load, and watch the diary prefill today's session from the active template. Browse an exercise library merged from wger, Free Exercise DB, and ExerciseDB, add custom movements, or bulk import your own catalog from a spreadsheet. Automatic PR detection, estimated one-rep maxes, volume and frequency charts, and dated progress photos with a drag-to-compare view show how training is trending. The built-in Trace AI coach reads your workouts, programs, records, and body stats to answer questions, log sessions, and adjust plans through Claude, OpenAI, Gemini, or a local Ollama model. Coaches can prescribe workouts, leave notes on individual sets, and review filmed set videos with comments stamped at the moment that matters, all with explicit consent from the athlete. Import years of history from Strong, Hevy, FitNotes, Jefit, or Garmin FIT files, keep logging offline in the gym, and sign in with OIDC through Authentik, Keycloak, or Authelia.

Training, meals, and body changes usually live in three different apps, and LiftCut puts them in one bilingual tracker where an AI agent helps keep the log instead of just drawing charts. Tell it what you ate, what you lifted, or what the scale said in plain language, in Chinese or English, and it prepares the entry from the exact numbers you gave, never inventing nutrients or weights, and saves nothing until you confirm it. Workout plans are editable rather than rigid programs, text import brings existing routines in, logging tracks completion and exercise performance, and personal records and PDF exports mark how far you have come. Food logs roll into nutrition summaries, and dated body measurements draw trend charts beside your training, so cause and effect sit on the same screen. AI training and nutrition proposals read your saved goals, restrictions, measurements, and recent actual loads first, then pass through extraction, strict validation, and an editable preview, and a proposal is rejected if the records it relied on changed in the meantime. Begin in the public no-sign-in demo or local-first guest mode, then create an account and migrate your history when ready, with offline queues holding entries until a connection returns. Providers span DeepSeek, any OpenAI-compatible endpoint, or a local vLLM server, so the intelligence can stay on hardware you control.
