One of Emma’s favourite exercises for working the lowers abs is knee tucks, and, according to her, such exercises can help to “alleviate lower back pain and improve posture”. To reap the full benefits though, you’ll need sliders, which are little discs you stand on during an exercise. They force you to fully engage your muscles throughout the movement, in order to stay stable and balanced.

1. To begin your knee tuck, get into a plank position on the floor, with your arms fully extended and body forming a straight line running from your head to your heels. Your toes should be on your sliders.

2. Making sure you engage your core and keep your arms straight, slide both knees in at the same time, stopping when they are just shy of your forearms.

3. Then, simply slide your feet back out to your starting position, and repeat ten times.
