How to do it

From hands and knees with a flat back, reach one arm forward and the opposite leg straight back to hip height, hold for two seconds without letting the hips tip, then return and swap sides.

Muscles worked

Primary: core · Also works: glutes, back, shoulders

Equipment

No equipment

Common mistakes

  • Kicking the leg up above hip height, which arches the lower back instead of extending the hip
  • Letting the hip on the lifted-leg side rotate up — imagine balancing a glass of water on your lower back
  • Rushing through reps; the value is in the two-second still hold at the top

Variations

  • Lift only the arm, or only the leg, while you learn it
  • Draw the elbow and knee together under the body between reps
  • Hold each position for ten seconds

Can't do this one? Swap it for

Take care: ABROFIT automatically removes this movement for anyone who has flagged a wrist problem. If that's you, use one of the swaps above and speak to a physio before loading it.
