The event asks residents across the emirate commit to 30 minutes of exercise daily, for 30 days – hence why it is often dubbed the 30x30 Challenge. There are thousands of fitness options available to take part in, and the best part is the sessions are all free. With offerings across a number of categories – from yoga and HIIT classes, to spinning, Zumba and boxing, as well as meditation and nutritional sessions, the events focus on both physical and mental wellness.
