Built for
serious athletes.

Every hard set scored against your own average. On your iPhone, your Apple Watch and your iPad.

The programs that built elite athletes.

Elite 12 Weeks. Triphasic. The Density Block. GVT. Periodised blocks built by the coach and proven on the athlete, with the methods inside them (EDT, clusters, APRE, waves) timed, loaded and refereed by the app.

Want your own? Build it on your phone, or open the Studio on a landscape iPad: drag sessions between weeks, periodise a block and see the hard sets per muscle before you train them.

PRE SZN Programs tab: continue PRE SZN's GVT, then the Strength, Running and Single sessions libraries

Every session ends with a score.

Full-time, 10–0. Every hard set contested against your own four-week average, every record banked. You never wonder whether it was a good session. The score tells you.

Each hard set (RIR 1–3) is scored against your line the moment you log it. Warm-ups cost nothing. A record always pays, whatever the line says, and it stays on the ledger.

PRE SZN full-time report: 10–0 against your own 1 Aug session, 4 PRs, set points and hard sets

Every set, contested.

Weight, reps, RIR, logged in seconds, with your line to beat printed on every row. Each hard set is scored the moment you tick it. Records always pay.

Last time’s numbers sit in every row, rest runs itself, and the scoreline at the top tells you where you stand against the plan all session.

Log it from your wrist.

Your session runs on your Apple Watch. Turn the crown to set the weight and reps, bank the set, and the record lands on your wrist. Heart rate through every set and every rest.

Wrist trace reads the Watch’s motion sensors through the set. It finds your reps, times each one, measures the speed you lost, and puts an estimated max for the set against your line. End the session on the Watch when you’re done.

PRE SZN on Apple Watch: 140 kg × 15 logged from the wrist, a record, you lead 3–0
PRE SZN wrist trace on Apple Watch: Incline Barbell Press, 5 reps, 49% velocity loss

Your mates are on the scoreline.

Add rivals and play a season. A weekly league counts what you won. Go live and friends join the same workout from anywhere, or from across the gym, with every set they bank beside yours.

Share a session as a link and anyone can open it and train it, even before they sign up. Share a whole program the same way, or post your full-time report.

PRE SZN Compete tab: rivals, Live Match (start, join, nearby), results, the weekly league and a rivalry call-out

Structured speed work. Tracked.

Sprint intervals, repeats and runs with GPS, programmed like your lifts. Warm-up, work and rest are set before you leave the line.

Run 100m sprints ×8, 200m or 400m repeats, or a free run. GPS tracks pace, distance and splits, and Apple Watch adds heart rate.

PRE SZN speed session: 100m sprints x8, warm-up, sprint and rest intervals

Your body, read every morning.

HRV, resting heart rate and sleep from your Apple Watch, against your own normal. Not a population chart. Yours. You know what you have before the first set. Then you use all of it.

HRV stability puts last night’s reading on your usual range, night by night. It sits beside your scoreline, so a big session is never a guess.

iPad Studio

Plan a block on a landscape iPad. Drag sessions between weeks, periodise linear, block, undulating or rep descent, apply set schemes in bulk, and see hard sets per muscle before you train them. Weeks you’ve trained are never rewritten.

Connect your own AI

Pro members create a personal key and plug their own AI into their training. Read sessions, records and lines, and write a program straight into the app, through a REST API or an MCP server.

How it works

Coach and morning brief

An AI coach that reads your training and answers in plain English. A morning brief on how you’re adapting, and a review of every week.

Beat your average.
