See your current load, fitness, fatigue, form, recovery, intensity balance, and efficiency—then explore the charts behind every signal.
Current state, recovery-aware readiness, recent volume, and exact load-model values in the same hierarchy used by Training.
See how Form, freshness, intensity, efficiency, and power change over time, with readiness, recovery, and sleep views available in Training.
Explore your sport's training mix, compare matching builds, and follow power capacity and long-session durability with the evidence behind each result.
Start from a preset or arrange Curated, KPI, Custom, and Map tiles yourself. Each tile keeps its own filters; maps add style and marker-clustering controls.
Compare heart rate, power, altitude, depth, pace, and more in synchronized charts. Inspect intensity zones, grade-colored elevation, inverse depth, aerobic durability, and cadence versus power. Switch between distance, duration, or time where supported, then select a range for stats or zoom in.
Build your next workout, save your favorites, and organize your plan into named phases. Plan for running, cycling, swimming, walking, hiking, rowing, or strength.
Start with one standalone workout, or organize dated plans with phases such as Base, Build, Recovery, or Taper. Use your own names, dates, and colors, with date shifting and history.
See your interval profile as you build. Set time, distance, or lap-ended steps, add repeats and heart-rate, power, pace, or cadence targets, then reorder or duplicate blocks. For strength, build exercises, sets, reps or holds, load, and rest.
Keep favorite sessions in your Workout Library. Add a saved workout to one date or repeat it across selected days, in a plan or on its own. Each scheduled copy stays independent.
With separate Training permissions, compatible MCP clients can read your schedule, assess provider compatibility, and prepare bounded plan, workout, or delivery changes for your approval.
Send compatible workouts to Garmin, Suunto, or Wahoo with Pro. Choose a plan to sync or send a workout on its own.
See standalone workouts, active-plan workouts, and phase labels beside completed activities without adding them to recorded totals or Training analysis.
Follow sleep, heart rate, HRV, and body measurements over time. Bring supported Garmin, Suunto, and COROS health data together, compare each source, and add your own measurements.
Explore sleep duration, stages, and overnight readings, with each provider clearly identified.
Follow resting heart rate and HRV over time. Compare nightly HRV with your personal range when enough history is available. Add context with notes about travel, sickness, stress, and time away.
Log blood pressure, weight, body composition, blood oxygen, and VO₂ max. Follow your readings over time alongside imported health data, with manual entries clearly labelled.
Explore sleep, readiness, training, measurements, and recent activities in one conversation. The Assistant answers from your current data—not generic fitness advice.
Start with today, a trend, or a recent workout. Ask follow-up questions without starting over.
The Assistant draws from sleep, recovery, training, measurements, and activities when your question needs the broader context.
Each answer shows the data behind it, so you can see exactly what supports it.
Your data, current evidence, conversational answers.
Connect ChatGPT or Claude through permission-scoped MCP. Ask them to analyze your training or prepare a bounded Training-plan proposal grounded in your approved data. Timeline note, activity-tag, and Training changes each require separate access and your client’s approval; location access remains separate.
Compare same-session recordings from watches, bike computers, and sensors. Set reference and test devices, auto-align their timelines, and turn GNSS and sensor differences into repeatable evidence.
