I will be 67 in August. I started exercising as a teenager in an attempt to achieve thin thighs
heh heh, still hasn't happened. I also discovered yoga as a teen and have practiced all my life. In my 20s I was an avid cyclist and discovered "aerobics" group classes in 1979. Since then lots of group classes, straight up dance classes (ballet, jazz, Afro-Caribbean), hiking, cycling, jogging--which I never learned to like etc.
I discovered videos for exercise when I moved to Hawaii in 1995 and couldn't find any group classes I liked. I discovered VF shortly after that and have been using videos ever since. I like group water aerobics but that is a thing of the past for me now, but I still hike, cycle, swim, and do videos.
