Coaching, periodized

Programs that adapt — delivered to the phone.

Meso is where coaches design periodized training and deliver it straight to their athletes' phones. An AI agent drafts the week-to-week adjustments; the coach approves them. Athletes log their sessions and watch their lifts climb.

Design

Periodized, by the week

Build mesocycles, weeks, and sessions in a spreadsheet-fast designer — by load or %1RM.

An athlete's session view on a phone — exercises with reps, load, and RPE, and a circle to check off each set.

Deliver

Straight to the phone

Send a week straight to an athlete's phone; they get it as an installable app with offline logging.

The AI agent's review screen — a joint-friendly exercise swap and a load progression, each with a rationale, waiting for the coach's approval.

Adapt

An agent that proposes

The AI agent reads the logs and drafts adjustments — you review and approve before anything changes.
