At Sunset Fitness in the Park, yoga and barre instructors from local studios lead free weekly classes in the scenic Georgetown Waterfront Park. (Georgetown Business Improvement District)

You don’t need a pricey gym membership or a ClassPass to get in shape in the final days of summer. In fact, you might be better off without one: D.C. has plenty of free outdoor workouts to choose from. Here’s a sampling.

Movement Mondays
Chinatown Park, Sixth and I Streets NW
Need a post-work pick-me-up on Mondays? Crunch Fitness’ Movement Mondays series has two more sessions left. Next week, you can get your Zumba on; Aug. 28 is a general bootcamp class. There’s no equipment required for the classes, which run from 6:30-7:30 p.m. — just show up ready to get moving.

TriFit exercise series
Farragut Park, 912 17th St. NW & 2100 M Street
If yoga, barre and Pilates in the park sound like a winning combination, grab a mat and get ready to hold those poses. The Golden Triangle BID hosts a series of weeknight happy hour classes led by certified instructors. Practice yoga on Tuesdays at Farragut Park, barre on Wednesdays on M Street, and Pilates on Thursdays back at Farragut. Classes, which run from 5:30-6:30 p.m., will be held through Sept. 28.

Sunset Fitness in the Park
Georgetown Waterfront Park, 3303 Water St. NW
A trio of local yoga and barre studios — Down Dog Yoga, barre3 and CorePower Yoga — lead the last three installments of this Georgetown BID series. Classes start at 6 p.m. on Wednesdays and run for about an hour. Participants are asked to bring their own mats, but bottled water and snacks will be provided. Register online via Eventbrite, as space is limited.

Get Fit Like That’s strength class
The Yards Park, 355 Water St. SE
If you’re looking to get those abs, biceps and calves popping, head to Yards Park on Wednesday mornings at 6:30 a.m. through Aug. 30. Personal trainer Sharita Jennings, of D.C.’s Get Fit Like That, will lead participants in an hour-long workout designed to build and tone your muscles.

Thursday night kayaking
The Yards Marina, 1492 4th St. SE
Make plans to duck out of work early and hit the water for the next two Thursdays. Anacostia Riverkeeper, an advocacy organization dedicated to protecting and restoring the Anacostia River, is leading Washingtonians on a guided kayak tour of the body of water. The two-hour treks depart The Yards Marina’s public dock at 5:30 p.m. and serve as a good arm workout (especially compared to happy hour). Kayaks are available on a first-come, first-served basis, but can be reserved by emailing info@anacostiariverkeeper.org.

Morning bootcamp with Balance Gym
Canal Park, 200 M St. SE
Start your weekend off right with a pair of early-morning bootcamps hosted by Balance Gym. Thursdays and Fridays at 6:30 a.m. through Aug. 31, instructors from the local chain will lead participants through an intense, hour-long workout at Canal Park. All you need to bring is yourself and (if you’re smart) a water bottle.

DC Dragon Boat Club beginner practices
Gangplank Marina, 600 Water St. SW
If you’ve ever wondered what it would be like to race in a dragon boat with 20 other people to the beat of a drum, what are you waiting for? The DC Dragon Boat Club offers free beginner practice sessions for anyone interested in learning about the sport (and how to flex your rowing muscles). Classes run from 8:30-10 a.m. every Saturday. A waiver is required to participate. Sign up at dcdragonboat.org.
