Core
TRX Obliques
A high-stability suspension exercise designed to build rotational core strength and lateral abdominal definition.
How to perform.
Follow the sequence — setup is half the lift.
Adjust the TRX straps to mid-calf length and place both feet into the foot cradles while facing away from the anchor point.
Assume a high plank position with your hands directly under your shoulders and your body in a straight line from head to heels.
Engage your core to stabilize your hips and pull both knees toward your right elbow in a controlled, sweeping motion.
Squeeze your obliques at the peak of the contraction before slowly returning your legs to the center plank position.
Repeat the movement by pulling your knees toward your left elbow, ensuring your hips do not sag toward the floor.
Continue alternating sides while maintaining a steady tempo and keeping your shoulders stacked over your wrists.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Allowing the lower back to arch or the hips to pike too high during the transition.
- Using momentum and swinging the legs rather than engaging the core for control.
- Letting the shoulders drift backward away from the hands which increases joint strain.
- Failing to maintain full tension on the TRX straps throughout the set.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
