Right now, my ebike is my sole form of regular, sustained-periods exercise. Comprised of a 30-minute morning office commute many days this summer (opting for lighter pedaling effort / no significant exertion, to prevent a sweaty arrival) and then generally a ~90 minute evening ride back home (in which I aim to work harder for much, if not all of that ride), plus weekend rides (generally planning to work up a sweat at some point(s) along those rides, but not always for the entire ride.)
As we approach winter here (D.C. area) I need to figure out an alternative, since I expect weather to curtail my biking opportunities. (Right now I'm very much a fair-weather -- meaning dry, and above freezing -- biker.) Thinking of trying out 9 Round gym for the winter (a franchised 9-station circuit concept with kick-boxing elements.)
