You don't need crunches to build strong abs, just these eight 'deep core' exercises

From relieving lower back pain to improving balance and coordination, there are more reasons to strengthen your core than a lean stomach. It's important to know the difference between abs vs core training too, as the abs make up just a small part of your midsection muscles. 

If you want a comprehensive core workout you need to target your deep-seated stomach muscles, and that's exactly what this session from Sweat app trainer Britany Williams sets out to do. 

There are eight moves in total, and to do them you'll need a small exercise ball, a resistance band, and a pair of dumbbells. However, Williams suggests swapping these for a pillow, a pair of leggings and a couple of filled water bottles if you don't have this equipment at home. 

Complete the exercises back to back for 20-30 seconds each, and repeat this eight-move circuit for a total of three rounds to finish the workout. Williams demonstrates each exercise in the video below, so take note of her form before starting.

Although people use them interchangeably, your abs and core are different. Most people use abs to describe the rectus abdominis; the muscles found at the front of the stomach, responsible for the sought after six-pack shape. 

These are part of the core, but they work alongside many other muscles like the internal and external obliques, transverse abdominis, pelvic floor and multifidus to carry out vital functions such as stabilising your spine and allowing you to twist and bend your trunk.

Williams' core workout hits all of these muscles, rather than just focusing on the abs with sit-ups and crunches. Or, in her own words: "This abs workout targets your deep core function, not just the superficial parts! (Though it helps for that too!)"

To get the most out of this session, squeeze your core and think about really using your midsection muscles to initiate each of the movements. This will help activate mind-muscle connection, which can increase activity in the targeted muscles.
