I built ZeroPhase because the SEAL prep guide was hard to follow. Now today's workout and everything you've done are on one screen: no flipping through the PDF, no spreadsheet.

Built from the Naval Special Warfare Physical Training Guide. Page updated October 21, 2026.

For anyone preparing for Navy SEAL BUD/S who wants the NSW training guide structured into a daily program. Not a substitute for a custom program designed by a professional coach.

Still choosing what to train with? Every option the AI engines name, each fact with its own source and the date we read it.

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.
