Free fitness classes in Boston to shake up your workout routine

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.

Get a weekend wakeup call

InkBlock in the South End is hosting a 10-week class series sponsored by Capital One starting Feb. 27 called shrINK @ INK. Each Saturday morning will alternate between instructors Lauren Hefez (starting Feb. 27) for pilates fusion boot camp and Eliza Shirazi (March 5) for kickboxing-inspired 13-round class called Kick It. The hour-long classes run through April 30 and are open to all levels. Participants are asked to RSVP ahead of time and bring their own mats.

Every Saturday starting Feb. 27 through April 30 at 10 a.m.

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 onlineor follow @Athleta_Newburyfor more info.
