Today was a cross training day. I decided to head over to the gym and use the stationary bike. I am not big into the bike at all, but I have heard it's good for your cross training day so I sucked it up and used the bike. It wasn't all that bad either! I took a magazine with me and read while I biked for 48 minutes/10 miles. I think I will start using the bike more often. I also ended up strength training for back muscles. I love being in the gym during the summer. I never have to wait for any of the machines or a bench in the free weights area.
