Oops - forgot to log that I had a session last Tuesday, the 15th. It was ~54 credits, mainly focused on aerobics and yoga.
Last night I had a 43-credit session where I did aerobics and strength training. My weight was down a negligible amount. Hey - I'm nothing if not consistent!
I'm kind of getting in a groove of starting with the long run (although I unlocked free run last night, so maybe I'll try that next time), advanced step, free step, and hula hoop. Those definitely get me warmed up and my heart rate going. I've been avoiding the strength training exercises because several of them just plain suck. However, I had unlocked a ton of them while I was ignoring them, so I went and tried all of them again. I ended with the Lotus Focus balance game where you sit without moving for 1.5 minutes to cool down.
