Lawrence residents curious about the city’s fitness classes will be able to try some out for free beginning next week.

The Lawrence Parks and Recreation department announced this week that it will be offering free demonstrations for about a dozen classes, including interval cycling, kickboxing and yoga, according to the news release.

The “try before you buy” free demonstrations begin on Tuesday and are open to those 15 and older. The demonstration classes will be held at three of the city’s recreation centers: Community Building, 115 W. 11th St.; East Lawrence Recreation Center, 1245 E. 15th St.; and Sports Pavilion Lawrence, 100 Rock Chalk Lane. All the classes that will be demonstrated will be available during the summer session.

No registration is required for the demonstration classes, but some classes may be limited due to equipment and will be available on a first-come, first-served basis, the release said. For more information, residents can contact Recreation Instruction Supervisor Jo Ellis at 330-7355.

Descriptions and schedules of all the city’s fitness classes are available on the parks and recreation website, lprd.org. A full schedule of the free demonstration classes is as follows:
