Hello, welcome to DeCosmo Fitness. My name is Adam DeCosimo. I am a certified personal trainer, based in LA. In this site my goal is to share the fitness knowledge and experience that I have gained throughout my life with the world to teach you what exercises to do, how to workout effectively, and reach your fitness goals. Physical fitness should be as important to us as the air we breathe. However, working out and getting physically fit does not have to be dreadful. Instead, your personal training experience should always be safe and fun. For example, one of my favorite fitness activities is to hike. Hiking is a great form of exercising and builds both endurance and strength.
