YMCA Cardio

I was planning on going to Cycling class today but all classes at the YMCA are cancelled through Monday due to 'poor air quality' because of the fire.  Instead I just used the cardio machines.  I did 20 minutes on the exercise bike, 15 minutes on the elliptical machine and 15 minutes on the treadmill (walking briskly, I didn't feel like running).  It wasn't ideal but at least it was something.  I'm really not good at motivating myself when it comes to working out.  I need someone instructing me on what to do.  I'll come back to the YMCA when classes are back on.
