Hi everyone,

Due to my schedule it is very difficult for me to do 3 days of cardio per week. What are the pros and cons of doing 3 hours of zone 2 cardio once per week?

addendum - I guess my schedule is not the only thing making me want to do all my cardio in one day/week. I live in England. No car, lots of walking. Car is not a necessity right now. If I go to gym and only lift (even on leg days), I still have a lot of energy to do my daily stuff. But if I do cardio (even 45 minutes zone 2) I am fine in gym but after gym I don't have much energy.

that's why, I want to do do all my cardio on the same day (Sunday) and get over with it for the week.

Thanks
