Same here - it's great for range of motion. Initially, my goal was just to keep moving the seat forward one notch every other month. I moved in 9 notched before I decided I'm as far as I'm going to get.
Now my workout is 15 minutes on the bike (alternating 1 min low intensity, 1 min high intensity), then shooting baskets (20 free throws, around and back midrange jump shots (5 spots about 3 feet inside the 3-point line), 3-point shots (same pattern), then LifeFitness weight machines circuit training.
During HS baseball season, my workout is umpiring 4 nights a week. Mar-Apr, Aug-Sep). That's my main motivation for the other workouts.
I like to ride off road and paved trails and I used the Nordictrack to stay in shape when I couldn’t ride outside. Cycling is a great workout for knee muscles and cardio while being low impact on joints.
