Based in Torrance, California, AB Turn USA is a company dedicated to innovative products that promote fun, fitness and a healthy lifestyle. Hui Yan, an engineer and inventor, began developing the Ab Turn 360 in 2012. Hui had already engineered groundbreaking mobility products including the PumGo scooter, and the Dashbike, but his real passion was health and fitness. When he saw his daughter playing with a hula hoop, an idea was born. Hui’s vision: an exercise machine to revolutionize the way we perform core and cardio exercises.
