Monica Reed-Tremmel — Aerial Tricks Basics & Aerial Sculpt, Pole & Bellydance

I cannot imagine my life without fitness related movement. If the years have taught me nothing else, I know with certainty that there are no magic programs, pills or gurus that will make a person fit and fabulous forever. To have lasting success, fitness is something that one incorporates in to their life journey. The pursuit of fitness offers its own unique challenges and payoffs depending, as so many things in life do, on what you put in to it.
Personal experience has shown me that because everyone is busy and there are never enough hours in a day, fitness goals are more attainable when they are realistic for your life and when the fitness activities are enjoyable and fun.
Running, weight lifting, Pilates, yoga, dancing, poling, Piloxing and now aerial hammock; all have been an important part of my life and my overall physical and emotional health. I have been a student, performer and instructor of Middle eastern dance for the last 17 years. I ran races and took so many different classes! I have been a certified Piloxing instructor for 2-1/2 years and in 2014 I earned my certification as an instructor of aerial hammock play and fitness!
At Club B-Fit, I invite you to share my passion for fun in fitness by trying one of our aerial hammock classes. Join me, and enjoy your workout, challenge your body and build your confidence like you never thought you could!
