deicide i always just walk when i do cardio. the key is a brisk pace and doing it for at least 45 minutes.
and YES, i cant fucking stand cardio ! its the most boring thing ever! i want to cry after about 30 mins ! LOL.. an ipod with soem of your favorite tunes will help, it helps me...ALSO, doing cardio indoors really blows, if you are outside walking to a place and back, take a route withpeople and cars and scenery... it will go by super fast and be much less painful
