How to do it

1. Stand with feet shoulder-width apart holding a dumbbell in one hand at your side, the other hand behind your head or on your hip.
2. Bend sideways at the waist toward the dumbbell as far as comfortable.
3. Use the opposite obliques to pull yourself back upright.
4. Finish the set and switch sides.

Tips

• Bend only sideways; do not lean forward or back.

Common mistakes

• ✗ Holding weights in both hands.

  Why it hurts: The weights cancel out and you just flex the spine side to side.

  ✓ Instead: Hold one weight, bend slowly to the side and return by pulling up with the opposite obliques.

• ✗ Twisting or leaning forward while bending.

  Why it hurts: Combined side bending and rotation loads the discs.

  ✓ Instead: Move only sideways, as if between two panes of glass.
