What a workout!

I've been doing an aerobics workout via the W.i.i off and on for a while now.  Today, I decided to put "feet" on the balance board to boost it to 4 inches high.  Oh. my. goodness!  My legs were like spaghetti after the first 3 minutes!  (Yes, I'm a wuss.)  I'd have expected it if I didn't already work out using the same routine, but I did not expect the intensity to jump so drastically.  There are three 10 minute reps in the routine.  After the first one, I had to ditch the step and I skipped the 3rd one altogether.  I guess I'll have to start out slowly and build up to it.  On the bright side, Jax seemed thoroughly entertained by the whole process.
