I'm nineteen years old and I have about two weeks left before I go back to school. All summer I have been going to the gym and lifting for about an hour but it's not really doing it for me because I still don't have the results I want. I want a six pack, and obviously its really hard; I think that I just haven't been doing enough cardio. So starting yesterday, I started a workout where I wake up and do a three mile interval run of 30 seconds as fast as I can go and then two minutes down. Then I have protein powder and eat a yogurt with blueberries. I wait about an hour and a half and then I go to the gym where I do elliptical for thirty minutes, again 30 sec up, 2 minutes down. Then I lift, just doing a circuit on all of the weight machines, three sets of twelve. Then I do the stationary bike for 20 minutes pretty hard so my heart rate is around 160-170 the whole time. Then I come back, have more protein powder, eat lunch, and then relax for about an hour before doing a 20 minute ab workout. Then I take a nap and eat dinner. Is this too much? I feel like it isn't but I also don't want to enter a catabolic sate and start losing muscle instead of fat. I'm eating super healthy; yesterday I felt like I should've eaten more calories but I was so full. Is there anything really bad about what I'm doing? Thanks.
