24X Olympia winning coach Hany Rambod answers the question of whether cardio can destroy muscle building. If you're eating too little, overtraining, or doing too much cardio - absolutely, it's possible.
Always start with 20-30 minutes of cardio and then work your way up. Should your cardio be fasting? No. In a competition prep situation, Hany recommends starting fasted cardio several weeks into your preparation 12-16 weeks before the competition, then increasing cardio to 30-45 minutes and you can add a second session.
You can go up to 60 minutes of cardio if you're really out of shape, up to twice a day, but the key is not to get so out of shape that you're forced to do this. You want to stay in the 20-30 minute cardio range.
Pro tip: If you don't eat right, especially undereat, or don't rest properly, you will lose muscle. IsoJect, ultra-pure whey isolate protein, is a great way to replenish your protein with a clean, fast-acting protein post-workout.
