  • Goals become training blocks Set a goal and Mesos turns it into planned workouts and mesocycles you can follow.
  • Built around real constraints Train for any exercise or combination of exercises with plans that fit your schedule, equipment, and level.
  • A clear next workout Open the app and know what to do next, why it matters, and how it connects to your goal.

Milo helps you train smarter.

  • Ask training questions Use Milo to understand your plan, swap sessions, or get practical guidance before you train.
  • Feedback after workouts Record what happened and get useful feedback on effort, consistency, and what to focus on next.
  • Adjust future training Mesos uses completed workouts and progress history to help future sessions adapt over time.

Built for progress, not just activity.

Your training history should help you make better decisions. Mesos keeps the full record of what you planned, completed, measured, and improved.

  • Everything you complete Planned workouts, completed workouts, exercises, routes, routines, and notes stay connected.
  • Signals that show progress Track goals, measurements, streaks, volume, consistency, and training history without piecing it together yourself.

Log any workout.

Track the training you actually do, whether it was planned ahead or decided on the day. Every workout adds to a history you can build on over time.

  • Start without a plan Open Mesos and log the workout you are doing today, even if it was not generated by Milo.
  • Record the details Capture exercises, sets, reps, loads, notes, routes, duration, and completed sessions.
  • Keep it in your history Ad hoc workouts still count toward your training record, progress history, and future context.

Stay accountable with your people.

Training is easier to sustain when progress is visible. Follow friends, share completed workouts, and support consistency.

  • Follow training progress Keep up with what friends are working toward, from strength blocks to running goals.
  • Share completed workouts Completed sessions can become visible progress, not just private data buried in a log.
