Setup

  1. Lie flat on your back with knees bent and feet flat on the floor, spaced hip-width apart.
  2. Hold a single dumbbell horizontally with both hands in a close grip, resting it against your upper chest.
  3. Tuck your chin slightly and engage your core to press your lower back into the floor.

How to do it

  1. Exhale as you perform a controlled sit-up, keeping the dumbbell tucked close to your chest until your torso is upright.
  2. At the top of the movement, rotate your torso to the left, then to the right, keeping your spine long and the dumbbell close to your midsection.
  3. Return to the center and immediately press the dumbbell vertically overhead until your arms are fully locked out.
  4. Lower the dumbbell back to your chest and inhale as you slowly roll your spine back down to the floor one vertebra at a time.

Form checklist

  • Keep your feet glued to the floor throughout the entire repetition.
  • Avoid rounding your shoulders or hunching forward during the twist and press phases.
  • Ensure the rotation comes from your waist and ribs, not just your arms.
  • Maintain a vertical torso during the overhead press to avoid straining the lower back.

Pro tips

  • For maximum oblique activation, exhale forcefully during the Russian twist phase of the movement.
  • Focus on the 'eccentric' phase of the sit-up; lowering your body slowly builds significantly more core strength than the upward phase.
  • Keep your elbows tucked during the press to emphasize triceps and anterior deltoid engagement.

Make it harder

  • Perform the entire sequence with your feet hovering 2-3 inches off the floor in a V-sit position.
  • Add a 2-second pause at the peak of the overhead press to increase the stability demand on your core.
