I'm in the gym 5-6 days a week... with the following down
cardio 5 days a week for 1 hour, stretching 30 min
weights 5 days a week for 1.5 hours
(cardio is done in the morning, weights in the pm, no cardio on day after leg day, occasionally cardio is done by itself on one day)
total of 15 hours a week... seems like sooo much more (some weeks it is)
i guess i don't really track it based on hours, as long as i get it all done, i'm happy
