Does your gym offer spin classes? I find it hard to be motivated on a plain exercise bike outside of a class. With a good instructor, you can get a tremendous workout.
That is correct.
However, I got burned out on the spin class scene. The way I got motivated indoors is working with an online training program. I get a little email each day giving me my work out ( intervals, cadence, strength, recovery etc) and that works great for me.
