How to do Seated Twist (Straight Arm)

01
Setup
Sit on the floor with your knees bent, feet flat on the ground, and lean back slightly to engage your core. Keep your spine long and chest open.
02
Setup
Extend both arms straight forward at shoulder height, bringing your hands together or interlocking your fingers, keeping your elbows slightly soft.
03
Exhale as you slowly rotate your torso to one side, leading with your chest and keeping your arms straight and parallel to the floor. Focus on squeezing your obliques.
04
Inhale as you return to the center with control, maintaining constant core engagement and a stable lower body.
05
Exhale and repeat the rotation to the opposite side, ensuring your hips remain relatively stable throughout the movement.
06
Continue alternating sides for the desired duration or number of repetitions, maintaining a steady pace.

Tips

Focus on controlled movement rather than speed to maximize oblique engagement and prevent momentum from taking over the exercise.
Keep your gaze following your hands to encourage full spinal rotation and maintain a neutral neck position throughout the twist.
Maintain a consistent slight lean back throughout the entire exercise to keep constant tension on your abdominal muscles, especially the obliques.
If you feel lower back strain, sit more upright and reduce your range of motion until your core strength improves.

Common mistakes

Rotating too much from the shoulders and arms instead of the core reduces oblique activation; initiate the twist from your waist, using your obliques to rotate your entire torso.
Allowing hips to shift or lift off the floor indicates a lack of core stability; keep your hips anchored and stable, focusing the rotation primarily in your upper body and waist.
Holding your breath or breathing shallowly can hinder core engagement; breathe out as you twist to engage your core more deeply and inhale as you return to the center.
