My youth hockey.
I joined a fitness program to become not only stronger but also improve my balance and my flexibility.
I attend this class two times a week and do in-line skating as weather permits.
I also participate in a 35-and-older hockey league on Mondays, 50+ hockey league on Thursdays, and on Friday I play with a group ranging in age from 16 to 78.
There are still many collisions and knockdowns. So, keeping fit is essential for keeping up... At age 78, I'm doing pretty good.
My
doctor diagnosed rheumatoid arthritis. My knees would just ache, I was so stiff.
