Forget sit-ups — you only need 10 minutes and 3 moves to build a stronger core and boost your posture

Sit-ups are a great way to work your midsection, strengthen your abs and develop your core, but they're also not that exciting. If you're after a way to liven up your core workouts, try this trainer's three-move abs workout instead.

You don't need any equipment to get started, so it's an ideal option if you're on the go, at a busy gym, or want to squeeze in a mid-section session when you have 10 minutes to spare. But it can make things more comfortable on the floor to roll out one of the best yoga mats.
