A tummy crunch is a specific abdominal exercise designed to strengthen your core. Itβs a scaled-down version of a sit-up, focusing on the upper abs. Think of it as a mini sit-up π€. You lift your head and shoulders off the ground, engaging your abdominal muscles. Unlike full sit-ups, tummy crunches reduce strain on your lower back. Theyβre a great way to target those 'six-pack' muscles. Proper form is important to avoid neck strain.
