Emirates airline is the latest organisation to show their commitment to the 30x30 Dubai Fitness Challenge by releasing an athletic video. On Wednesday, Dubai's Road and Transport Authority announced their participation in the challenge, which is a pledge to do 30 minutes of exercise for 30 days from October 20. They shared a video of employees doing chin-ups on a bus, sprinting through the Dubai Metro and practicing yoga on an abra ferry. The videos respond to calls from Sheikh Hamdan bin Mohammed who is challenging the emirate to participate in the initiative he announced on October 2. Then, Dubai Police posted a video of officers telling the Crown Prince of Dubai that they had received his call and accepted the challenge. Next, Sheikh Hamdan called on Emirates airline to join on. The carrier replied with a single post that reads, “Challenge Accepted. Watch this space.” Dubai Electricity and Water Authority released their own video on Monday of women cycling past solar farms, running down desert highways and men hitting the gym. More than 45,000 people have already registered for the city-wide fitness challenge. People of all fitness and ages levels are encouraged to register at the <a href="https://www.dubaifitnesschallenge.com/">Dubai Fitness Challenge website</a>, which has nutritional tips and a calendar of events. Ambassadors include Essa Al Ansari, a 26-year-old Emirati who lost 70 kilograms, Amal Murad, an Emirati parkour athlete, and Dareen Barbar, a Lebanese fitness trainer who lost her leg to bone cancer at age 15 and had not set foot in a gym until her thirties. The month kicks off with a carnival in Safa Park on October 20. More than 1,500 free fitness classes will be offered around the city. Registration is open.
