cardio everyday?

I was wondering about doing cardio everyday, I have been told to do it every other day and give my body a rest. I have been doing 60 minutes everyday 3-4 miles. I also do upper body every other day and abs everyday.. I don't feel as good if I skip the cardio and just do the upper and lower body. but if I am hurting myself by doing to much I will cut it back please help.

Even once you're in a regular running regimen you should give yourself 1 day off a week. 6 days a week is fine, just never increase by more than 30% in one week, and you should only do the increase once a week on your "distance" day.

See when you use muscles, they do actually take damage - little microscopic tears.. Its ok though, its part of building muscle. When the body gets damaged, it grows back stronger. This means stronger muscles. But if you do the same thing every day your body never gets to repair itself. You also will lose some of the benefits of running if you do it every day, because your body gets used to the same exercise. Try cross training a little.

A day of rest is a good idea for cardio. You mentioned you do abs everday. Muscles need a to rest after you've worked them, so you should probaby only do abs every other day. That will allow them to heal and actually get stronger and more toned.

I do cardio everyday. I don't take a day off, but I generally have 1 day a week where I replace my running with a nice, brisk walk. It's less strenuous.
