Swimming involves nearly every major muscle group working in a synchronized "kinetic chain" to overcome water resistance. Propulsion is generated primarily through the upper body, while the core and legs provide essential stability and positioning. 🦾 Upper Body Propulsion
The rectus and transverse abdominis keep the body in a streamlined, horizontal position to reduce drag.
Proper core engagement prevents the hips from sinking, which is a primary cause of slowed momentum. 🦵 Lower Body & Kick
The chest muscles generate the power needed during the "catch" and initial pull phases.
