Stability ball exercises help strengthen the core (lower back and abdominal muscles). Having a strong core helps stabilize the entire body during daily activities.

Stability ball exercises engage your stabiliser muscles. Using your back and abdominal muscles to maintain your balance on the ball encourages good posture and balance.

Foods rich in complex carbs can be great pre-workout snacks. Complex carbs will slowly release energy during and after a workout. Foods with simple sugars will break down quickly, which can result in fatigue. Look for foods such as multigrain bread, beans, bananas, berries and sweet potatoes.

Studies show that exercise may help reduce symptoms of stress, anxiety and depression. Exercise releases powerful chemicals such as endorphins and serotonin, which improve mood and feelings of well-being. It can lower cortisol (also called the “stress hormone”) levels and support nerve cell growth in the hippocampus, a region of the brain that helps regulate mood.

Muscle mass affects the metabolic rate. Crash diets can cause muscle loss, which can slow the metabolism.
