Too much Cardio

[naug44]

What’s up everyone? I have a question about cardio. Is there such a thing as getting too much cardio? Does doing too much cardio effect muscle growth? At work, I walk 2 miles a day after lunch. I ride the stationary bike at home about 20 minutes a night. I workout on the speed and heavy bag 4 nights a week. Is this too much cardio? I lost weight and feel great.

Too much cardio can cause you to lose some muscle mass.

I do not think that is too much cardio. Your workouts are relatively short and spaced out enough to allow for recovery. You are mixing up the exercises as well if you said “I run 5 miles 6 times per week” I would be worried about the condition of your knees as well as possible over training. I know some runners who think nothing of running much more than this but they have become specialized to do nothing but run so normal rules do not apply.
