Intervals

My friend
and fitness director was at the gym yesterday
told me to do intervals.

High cardio for 1 minute
drop to a lower cardio for 1 or 2 minutes
then back to high cardio
keep this up for the entire work out
and my body will burn fat longer after I'm done working out.

Hey, I'm all about my body working long after I'm done!
So yesterday I jogged a lap on the indoor track, walked a lap.
Keeping this up for 35 minutes!
