Fitness matters in lifeguard training because a rescue demands a short burst of power after hours of stillness. Courses build swim endurance, tolerance for long shifts, and the strength to tow and extricate a victim.
Updated for 2026. This article was reviewed in 2026 and the guidance below reflects how the course is run now.
The course runs in two formats and both end at the same standard. In the classroom format all instruction, testing and skills evaluation happen in person.
Class size is capped at ten participants per instructor, with a second instructor or an authorized assistant added above that, so hands-on time per person does not fall as a class grows.
