After school on Tuesdays, Room 3301 is cleared of desks and filled with soothing music, dimmed lights and yoga mats. Physical education teacher Jennifer Kanwischer leads an intramural yoga class every Tuesday from 3:30 p.m. to 4:30 p.m. It is open to Oak Park and River Forest High School students and staff of all experience levels, and yoga mats are provided. Kanwischer said, “I just want people to show up and try it out, and they may lean into it, or they may not.”
