YS Team

Meet Ypsi Studio’s fantastic, fun, and well-qualified instructors and staff!

Alex Henderson

Since she was young, Alex Henderson has enjoyed an active lifestyle. Due to an injury in high school, she lost a lot of her athletic ability. She spent years in physical therapy trying to regain her previous strength and movement, but to no avail. In an attempt to remedy her damaged hip, she began hoop dancing, and it worked wonders. Not only was hoop dancing physically therapeutic, it also exposed her to a new community that relished in the flows of the body.  Shortly after, she began practicing aerial acrobatics and through these practices, was introduced to the world of yoga. After practicing for about two years, Alex decided to take her practice one step further and become a certified instructor. She attended and was certified through East Lansing Hot Yoga, RYT200, in East Lansing, MI. Her training was unique and diverse, exploring a multitude of styles and practices. A few years ago, Alex moved to Ypsilanti and is excited to be teaching yoga at Ypsi Studio!
