The pool is also closed for two weeks for maintenence. And I wouldn't have had the chance to get there today anyway.
So this evening I did the 'cardio-abs' workout for Power 90. I bet this program works if I actually use it for 90 days (I have done it on and off for a few days for about a year).
But it is a workout for today.
My NB717 that I bought 4 years ago (when I was still running pretty regularly) were getting pretty worn out. But I will keep them for foul weather running.
