Which should you pick?
- Pick Plank 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.
- Plank 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.
