Muscles worked

Primary

  • Abs
  • Obliques

Secondary

  • Erector spinae
  • Glutes
  • Quadriceps

Equipment

  • Body weight

Setup

  1. Stand with your feet wider than shoulder-width apart in a stable stance.
  2. Extend your arms straight out to the sides at shoulder height, forming a 'T' shape with your palms facing down.
  3. Engage your core and stand tall with a neutral spine and a slight bend in the knees.

How to do it

  1. Inhale as you hinge at the hips, keeping your back flat and arms locked in their wide position.
  2. Exhale and rotate your torso to reach your right hand toward your left foot in a smooth, circular arc.
  3. Inhale as you reverse the movement to return to the starting upright position with arms still extended.
  4. Repeat the movement on the opposite side, reaching your left hand toward your right foot, alternating sides for each rep.

Form checklist

  • Keep your arms in a straight line; do not let the trailing arm drop toward the floor.
  • Hinge at the hips rather than rounding your lower back to reach the floor.
  • Keep your weight centered over your mid-foot to avoid leaning too far forward or back.
  • Follow your top hand with your gaze to encourage full thoracic rotation.

Pro tips

  • Focus on the 'windmill' effect by reaching the top arm directly toward the ceiling to maximize the stretch in the chest and engagement of the trapezius.
  • Squeeze your glutes forcefully at the top of each repetition to ensure full hip extension and stability.

Make it harder

  • Hold light dumbbells or weighted plates to increase the resistance on the deltoids and obliques.
  • Slow down the tempo to a 3-second descent to increase time under tension for the hamstrings and core.
