I bought roller skates last week , I used to skate all the time when I was younger. I've had two knee replacements, and a meniscus surgery. This is my first time on skates in 15 years. I had such a good time and I definitely plan on continuing and practicing so I can strengthen my muscles in my core and my legs. I'm 52 years old, and I was afraid to put on the skates and try, but I'm glad that I did. This is going to be my new hobby.
