Exercise

Suitcase Carry

One heavy dumbbell in one hand, and your obliques have to fight the whole walk to keep you upright. It's the exact skill of carrying a car seat or a loaded grocery bag without folding sideways - trained deliberately.

How to do it

  1. 1

    Deadlift one dumbbell from the floor with a flat back and stand tall.

  2. 2

    Hold it at your side like a suitcase, arm straight and shoulder level - don't lean away or toward it.

  3. 3

    Brace your core and walk with short, controlled steps for 30-40 meters or 30 seconds.

  4. 4

    Keep your shoulders and hips level the entire way - someone watching shouldn't be able to tell which hand is loaded.

  5. 5

    Set it down, switch hands, and repeat on the other side.

Common mistakes

  • Leaning toward or away from the weight instead of staying vertical
  • Shrugging the loaded shoulder up
  • Choosing a weight so light your core never has to fight

Dad tips

  • Film yourself from behind once - a visible lean means tighten the brace or drop the weight slightly.

Same muscles, new angle

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.

Bicycle Crunch

A floor classic that works the obliques through rotation - the movement pattern behind twisting to grab something in the back seat. Done slowly and with intent, it's far more effective than the frantic version most people rush through.
