Calisthenics

Sit-Ups

Sit-ups are a core calisthenics exercise and one of the five scored events in the Physical Screening Test (PST). In the NSW preparation program, sit-up training follows the same progressive volume model as push-ups — daily targets scale based on the candidate's most recent PST max to maintain consistent overload.

PST Sit-Up Standards

Candidates perform as many sit-ups as possible in 2 minutes. The minimum qualifying score is 50 repetitions, with competitive scores reaching 80-100. Proper form requires the fingers interlocked behind the head, knees bent at approximately 90 degrees, and feet held by a partner. Each rep requires the shoulder blades to touch the ground on the way down and the elbows to touch or pass the knees at the top.

Sit-Ups in the Training Program

Sit-ups are trained alongside push-ups and pull-ups in the Push-Sit-Pull calisthenics block that appears multiple times per week. The rep targets are derived from the candidate's PST sit-up score using the same tiered progression brackets. A candidate scoring 60 sit-ups trains at a different volume than one scoring 90, ensuring the stimulus matches the individual's capacity.

Core Endurance Beyond Sit-Ups

While sit-ups are the tested movement, the NSW program supplements them with additional core work including planks, bridges, bird dogs, and supermans. These exercises build the trunk stability that supports every other activity in BUD/S — from log PT to ocean swims. The sit-up is the measurable proxy for overall core endurance, but the broader core program is what builds real functional capacity.

BUD/S Tip

Pace your sit-ups during the PST. Going all-out in the first 30 seconds and then struggling through the remaining 90 seconds costs reps. Find a sustainable rhythm.
