Mesos turns your goals, workout history, and feedback into structured training you can follow and improve over time.

Goals become structured plans.

  • 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 handles progression for you.

  • 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.

Show off your hard work.

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.
  • Accountability without noise Social features are there to support consistency and encouragement, not turn training into a feed-first app.
FAQ

Questions, answered.

Is Mesos an AI coach or a workout tracker?
Mesos is a training app for planning, tracking, and improving your workouts. Milo is the built-in AI personal trainer feature that helps with plans, questions, feedback, and progression.
Is Mesos actually suitable for hybrid training?
Yes. Mesos treats lifting and running as one training stack rather than two separate apps stitched together. Milo plans your strength and conditioning together, balances volume and recovery across both, and adjusts when one side starts eating into the other.
How does Milo balance lifting and running in the same week?
Milo plans your week around the goals you give it - a race, a strength target, or both - and sequences hard runs, easy runs, and lifting sessions so they support each other. When you log workouts and feedback, it adjusts intensity, volume, and ordering to keep you progressing without burying you.
What kinds of workouts can I track?
Strength workouts, runs with GPS routes, intervals, mixed strength-and-conditioning sessions, and everything in between. Goals, routines, mesocycles, measurements, streaks, and completed workouts all live in one history Milo can reason over.
Who is Mesos for?
Hybrid athletes, runners who also lift, lifters adding conditioning, and anyone training for more than one thing at once. It also works well for gym-goers, beginners, and people returning to training who want a real plan instead of a blank logbook.
