Love this topic!
I live and work in the country, but work in the city one day a week with my family. So, I decided that I want to try something fun, different and active that day after work and invite everyone to try it with me. So my husband and I came up with a list of city activities we could try including indoor rock climbing, putt-putt, swimming, bowling, etc. First try was roller skating, which none of us had done for 25-30 years. We had a blast, but it was harder than we remembered. We decided to do it again.
At Christmas the kids were jumping on the trampoline so I tried it with them. Very fun.
I also signed up for Zumba one day a week and love it. Glad horseback riding was mentioned, as I have been invited to do that. Haven't done that since I was a kid. And a friend invited me to try her Wii Fit. Once I decided, all these opportunities presented themselves!
