The great outdoors is the perfect free alternative to pricey gyms, but if you need an instructor to get you moving and can’t afford to go every week, there are a few options to get a high-end workout on the house.

Expand your horizons 

Athleta’s Newbury Street spacious shop regularly makes room for (honestly very awesome) classes from local trainers and instructors ranging from Barre-lates to BollyX. The classes are totally pro-bono and usually cater to a 9-5 schedule (with 6 p.m. and later start times) for fitness junkies hitting them up after work. Bonus points: Sometimes locally made goodies like Beacon Blend smoothies and Biltong prosciutto jerky will show up as post-class treats, so be sure to check the calendar ahead of time.

Schedule varies, check online or follow @Athleta_Newbury for more info.
