I remember doing Jane Fonda aerobics tapes for swim team pre-season conditioning in high school. These were brought in by other girls & we all did them together. I will not claim this as my idea.
My mom also made me do step aerobics with her a couple times. I was not coordinated enough.
I tried rollerblading in high school, but could never stop without wrecking. Just tossed the blades last year. It never really caught on in KS anyway.
Spinning was fun. I would still do that, but I work out at home now. I still like the big fitness ball too, but I bought a DVD last year that was super-awful. I'm still onto the P90X stuff and the treadmill. I have owned 2 treadmills, so I must like them. Oh, also still on the jogging stroller bandwagon. I wish I could get back into the mountain biking trend. We never found time to hit the trails after our second kid, but I still have the bike.
