If there's one area of your body it's worth strengthening, it's your core. This collection of mid-body muscles play a part in almost every movement you make, from squatting down to tie your shoes to putting your shopping away.
A lot of people use crunches and sit-ups to strengthen the core. These exercises primarily target the rectus abdominis (the abs), which are found at the front of your stomach, but they don't strengthen other important core muscles. To get a more comprehensive core workout, you need to do a wider range of movements.
