Heart-pumping, core-building and tush-tightening, Fluid Cycling in Wayne offers a spin class like no other. It’s the first in the country to employ RealRyder bicycles that move side-to-side, activating arms, abs and legs. Video technology displays scenery on a giant screen so it looks—and feels—like cycling uphill in the Italian Alps. Request a class with co-owner Shane Duncan, because it’s more fun to have an Aussie challenge you to go faster. 724 Lancaster Ave., Wayne, (484) 580-6754, fluidcyclingmainline.com.
