As the number of summer days fit for outdoor exercise dwindles, get one last fix of fresh air at the BOKX 109 American Prime patio. The Newton eatery invites yoga enthusiasts to its pool deck where instructor Leah Croteau will lead a fundamentals class on Sunday, September 27th. From 4:30-5:30pm, join Croteau and other yogis for a class that ends the weekend on a soothing note. Tickets are $25, available here, or $30 at the door. If you’re not too sweaty after, grab a drink inside or sit down to dinner and postpone the arrival of Monday morning.
