Whether you’re working toward six-pack abs or a stronger core and better balance, the key is consistency. And if you don’t enjoy your workouts, you won’t do them. While most ab workouts consist of planks and crunches, they aren’t the only way to tone your midsection. Far from it.

There are a ton of different ways out there to build a strong and dynamic core, and not all ab workouts are created equal. To build a strong core and achieve the six-pack abs you’ve always dreamed of, you need to be strategic with your ab workouts. It’s no longer enough to simply hit some crunches and call it a day if your goal is building a strong core.

The following workout is an AMRAP workout, which is an acronym that means “as many rounds as possible.” This type of HIIT exercise is an ideal way to trim your torso — no planks or crunches required!

Perform​ each of the following five exercises. Rest 60 to 90 seconds before repeating the entire set of exercises. Continue for 20 minutes.

1. Windshield Wiper:

Start by performing this exercise with your knees bent, especially if you have a previous back injury or back pain. Work your way up to performing this with straight legs as your core strength improves.

Windshield Wiper

How to:

  • Lie on your back with your lower back pushed into the ground.
  • Place both arms by your side at about a 45-degree angle.
  • While keeping your legs straight, lift your legs upward as far as possible.
  • Next, while trying to keep both of your shoulder blades on the ground, slowly move your legs and feet to one side of your body.
  • Once you have rotated as far as you feel comfortable, rotate your legs and feet to the opposite side.
  • Make sure to keep your core muscles engaged, and your arms pressed firmly into the ground the entire time.
  • That’s one rep.
  • Complete 5 reps.

  • Start in a mini squat with your knees slightly bent and your feet about shoulder-width apart.
