I decided to see what it was like using the bike machine at our gym. . . it seemed a lot harder than riding my real bike. My thighs got a workout for sure. I put it on a level 3 workout. Stayed in 1, 2 and sometimes 3rd gear. I did some light jogging and walking and about 50 or so crunches. Slowly but surely I will get more endurance. . . I hope!
I think I will go jump in the pool to cool off!
