Sprouts Farmers Market presents a free fitness series at Discovery Green. Instructor John Tran leads Core-Focused Yoga classes this fall, focusing on dynamic flow sequences and long-held poses that train the body for strength and flexibility. No pre-registration required, but participants must sign a waiver upon arrival. Bring a towel and water, as well as a mat for yoga classes. Yoga mats can be purchased in the office at Discovery Green between 9 a.m. and 6 p.m.
