Progress needs the details.

Every set, session, and effort feeds your next move.

Everything you train, in one place.

Lifting, conditioning, and the progress they add up to, all tracked in the app you already carry to the gym.

The problem with every other app is they only let you log. There’s no real way to plan ahead, so the program lives in your head or some spreadsheet. Kiron flips that. You sit down once, lay out the weeks, and after that you just open the app and press start.

Program the whole block. Then carry it to the phone.

Lay out weeks, sessions, sets, and progressions on a canvas with room to think. Drag days around, duplicate work, and update matching sets across an entire block without rebuilding it by hand. Then everything you write here, along with the PRs and history it earns, shows up on the phone you actually train with.

Training never goes exactly to plan. Sessions slip, weeks shift, life gets in the way. Kiron keeps you on it with reminders and a plan that moves with you. And the structure is the point: a review of eighteen studies found training to a plan produces significantly greater strength gains than training without one.
