Hi Joey......I've been doing the links you sent on legs and butt....as well others from your 6 day program.  You said to do legs 2-3 x a week.    How long should I work on the legs on a leg day.....around 45 mins to an hour?  With arm and core exercises.....which I'll do 2-3 x week.....would you say about 15-20 mins on each?  Also doing cardio around 30 mins.....doing my best to do 6 days.  Would a long brisk walk for about an hour be considered a cardio?  I know it is a cardio workout but wasn't sure if it was a fat burn type cardio.  Thanks Linda
