Core
Side Crunch
A precise lateral movement designed to isolate the obliques for improved core stability and definition.
How to perform.
Follow the sequence — setup is half the lift.
Lie on your right side on the gym mat with your knees stacked and slightly bent at a forty-five degree angle.
Place your left hand behind your head and rest your right arm across your torso or flat on the floor for stability.
Engage your obliques to lift your upper torso off the mat, bringing your left elbow toward your left hip.
Hold the peak contraction for one second while maintaining a neutral neck position.
Lower your torso back to the starting position in a slow, controlled motion without letting your shoulder blades fully rest.
Complete the set on one side before flipping over to repeat the movement on your left side.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Pulling on the neck with the hands
- Using momentum rather than muscle contraction
- Rotating the chest toward the ceiling instead of staying lateral
- Lifting the legs off the floor to cheat the range of motion
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
