How each one feels

Dead Bug

  1. Slowly extend one arm back overhead and the opposite leg out straight — at the same time — while you breathe out.
  2. Return to the middle, then do the other arm and leg. That's one rep each side.

Watch out for: Lower back lifting off the floor.

Sit-up

  1. Curl your head and shoulders up first, then the rest of your back.
  2. Sit up tall, then roll down slowly.

Watch out for: Yanking your neck.

Dead Bug: pros and cons

  • + No kit needed, so you can do it anywhere.
  • + One side at a time helps even out imbalances.
  • + Really focused on your abs.
  • − Harder to add weight in small steps as you get stronger.
  • − Takes twice as long because you do each side.
  • − Can be awkward if your body needs looking after, or during pregnancy.

Sit-up: pros and cons

  • + No kit needed, so you can do it anywhere.

Which should you pick?

  • Pick Dead Bug if you train at home, travel a lot, or want something you can do anywhere.
  • Pick Sit-up if you train at home, travel a lot, or want something you can do anywhere.
  • Dead Bug needs no kit, so it's great at home or when the gym's packed.
  • Dead Bug trains one side at a time, which helps even out imbalances.
  • Sit-up needs no kit, so it's great at home or when the gym's packed.
  • Honestly? Both work. The best one is the one you'll do consistently and add a little to each week.
