I just completed the Quiz: Test your Fitness IQ SparkPeople Fitness Quiz and have a Cardio question!
One question stated that Cardio should be 3-5 days a week, with 1-2 days rest in between....and one (#7) states that you should do 20 min of Cardio every day. ?! I'd never seen a reference for the second statement before.
Is the implication that we should do 20 min every day, but on 3 to5 of those days do longer, more intense Cardio workouts??
Thanks! I've still got a lot to learn apparently
