I met with the trainer at Planet Fitness today. I worked out for about 25 minutes. That's not very much time, but it was enough to make me ache everywhere. Yes, I am that out of shape. One nice thing about Planet Fitness is that they have massage chairs you can use. I sat in one for 15 minutes. Those chairs don't go easy on you. If you have a knot in your back the chair will get it out.
