Side Plank

The side plank builds the lateral core muscles that keep your spine stable when life loads you unevenly - a kid on one hip, a duffel in one hand. It's one of the most back-friendly core moves there is.

How to do it

  1. 1

    Lie on your side with your forearm on the floor, elbow directly under your shoulder.

  2. 2

    Stack your feet (or stagger them for balance) and lift your hips off the floor.

  3. 3

    Form a straight line from head to heels - no sagging, no piking.

  4. 4

    Reach your top arm toward the ceiling or rest it on your hip.

  5. 5

    Breathe steadily and hold, then switch sides.

Common mistakes

  • Letting the hips drop toward the floor mid-hold
  • Rolling the chest toward the ground instead of staying stacked
  • Putting the elbow too far from the shoulder, straining the joint

Dad tips

  • Too hard? Drop your bottom knee to the floor and hold from there.
