How to do it

Sit on the floor with your legs extended straight and a dumbbell at each shoulder. Brace your core hard and press one dumbbell overhead until the arm locks out, lower it back to your shoulder, then press the other side, alternating each rep.

  1. 1Shoulders and triceps doing the work with no help from your legs
  2. 2Abs and trunk bracing hard to keep you upright
  3. 3One arm locking out by your ear while the other resets

Common mistakes

  • Leaning back or flaring your ribs to press
  • Letting the dumbbell drift forward or the elbow flare wide
  • Shrugging your shoulders up toward your neck
