How to do Oblique Crunches Floor

01
Setup
Lie on your back on the floor with your knees bent, feet flat on the ground, and hip-width apart.
02
Setup
Place your right hand gently behind your head with your elbow flared out, and extend your left arm straight out to the side or rest it on your stomach.
03
Exhale as you lift your head, shoulders, and upper back off the floor, simultaneously twisting your right elbow towards your left knee, engaging your right oblique.
04
Slowly and with control, inhale as you lower your upper body back to the starting position, keeping tension in your core.
05
Complete all repetitions on one side before switching, or alternate sides for each repetition, focusing on a smooth, controlled motion.

Tips

Focus on initiating the movement from your obliques, imagining your rib cage drawing towards your hip bone, rather than just pulling with your neck.
Keep your lower back pressed firmly into the floor throughout the movement to maximize oblique engagement and protect your spine.
Control both the upward crunch and the downward release; avoid letting gravity drop you back down to maintain constant tension on the target muscles.
Breathe out as you crunch up and twist, and inhale as you slowly return to the starting position, coordinating your breath with the movement.

Common mistakes

Pulling on your neck during the crunch can strain cervical vertebrae; instead, keep your hand lightly supporting your head, letting your core muscles do the work.
Rushing through the movement reduces muscle activation; perform each crunch slowly and deliberately, focusing on the contraction and controlled release.
Lifting too much of your back off the floor can engage other muscles and reduce oblique isolation; only lift your head, shoulders, and upper back, keeping your lower back grounded.
