Foundation block, weeks 1 to 6

Week 2 of BUD/S Prep

Only the long days change: the run adds a quarter mile and the swim adds 100 yards. Everything else repeats. That small step is the size of every weekly increase on the long days for the next six months.

The foundation block

Weeks 1 to 6 build the base. Distances are short enough that a candidate who passes the PST minimums can finish every session, and the point is to establish the six-day rhythm: three runs, three swims, strength or calisthenics every day. Core work is two sets of each exercise. If a session feels easy, that is by design. Adaptation comes from consistency in this block, not from intensity.
