The diagonal reach on chair is a seated bodyweight core exercise that targets the waist, working the obliques along the sides of your trunk with help from the rectus abdominis. Because it's done from a chair with no equipment, it's an accessible, low-impact way to train rotation and anti-slump control, making it a good fit for beginners and seniors.
Cómo hacer el Diagonal Reach on Chair
- 1Sit tall toward the front of a stable chair with your feet flat on the floor about hip-width apart.
- 2Brace your core gently and lengthen your spine, keeping your shoulders relaxed and down.
- 3Raise one arm overhead, then reach that hand diagonally down and across your body toward the outside of the opposite foot.
- 4Let your torso rotate and flex slightly toward the reach, exhaling as you move and keeping the motion slow and controlled.
- 5Pause briefly at the bottom, feeling the stretch and tension along the side of your waist.
- 6Reverse the movement under control, returning your arm overhead and your torso upright as you inhale.
- 7Complete your reps on one side, then switch arms and repeat the reach on the other side.
- 8Finish seated and tall, releasing your brace once both sides are done.
Consejos de técnica
- Keep your core lightly braced throughout so the movement comes from your waist, not just your arm.
- Move slowly in both directions and control the return rather than letting your torso drop or snap back.
- Stay tall through your spine and avoid rounding or collapsing your chest as you reach.
- Keep your hips and seat anchored to the chair so the rotation happens through your trunk.
- Breathe out as you reach across and in as you return; never hold your breath.
Errores comunes
- Using momentum to swing the arm down, which lets your shoulder do the work and takes tension off the obliques.
- Slumping or rounding the lower back instead of staying tall, which reduces core engagement and stresses the spine.
- Lifting the opposite hip off the chair to reach farther, which cheats the rotation and shortens the range that actually trains the waist.
- Holding your breath during the reach, which raises tension and makes the movement feel harder than it should.
- Reaching only with the arm and not allowing the torso to rotate, so the obliques never fully engage.

A sensible starting point is 2–3 sets of 8–12 controlled reaches per side. Focus on slow, deliberate movement rather than speed or high numbers.
