Nathan Amy brought a gym to the beach. In fact, he can bring a gym anywhere in San Francisco. With his new fitness company Kokoda, Nathan uses a mobile fitness truck to bring a gym to you. The truck is loaded up with tons of fitness equipment. Nathan can pull in to any location, unload his equipment, and set up a fully functional gym in a matter of minutes. Most of the time, his gym is set up at East Beach right next to Crissy Field. He leads classes there six days per week. I recently joined Nathan at East Beach for his Functional Fitness class. Let me tell you, it did not feel like I was at the gym. On a crystal clear evening, I worked out as the sun set over the Golden Gate Bridge and a light breeze blew in from the bay. The view was incredible and the workout was intense. I was still feeling it a few days later! Nathan's journey to starting up Kokoda is an interesting one. He grew up in the Australian Outback and joined the army at the age of 17. After leaving the army, he worked various jobs in the private security sector in Kabul, Afghanistan. At a United Nations barbecue, he met the love of his life and that led him to San Francisco. Nathan lives in the Marina and shares his favorite spots there and throughout San Francisco.
