The method is not ours. Every workout, progression, and pacing table comes straight from the guide. ZeroPhase turns it into a daily plan.

The training guide is complete — and complicated.

Simply put, the guide has everything you need. The problem is that it's packed into a dense PDF full of tables and progressions. Candidates lose track by week 3 and end up winging it.

From PDF to daily action in 3 steps

Step 1

Sign up and take your first PST

Log your swim time, push-ups, sit-ups, pull-ups, and run time.

Step 2

Get a plan calibrated to you

Your program adjusts to your current fitness level automatically.

Step 3

Train day by day for 26 weeks

Open the app, see today's workout, complete it, track your progress.
