I've been on an axercise program recently that I consider to be pretty vigorous. The first two weeks involved a lot of hiking, weight lifting, some cardio (at least 30 minutes a day) but all in all at least 2 hours of exercise a day. The 3rd week I took it easy to let my body rest, I wasn't completely sedentary but I didn't lift and I just did some simple circuit training along with soccer practice and games twice a week. I'm on my fourth week and yesterday I got 2 hours of exercise buring nearly 600 calories. I usually burn at LEAST 300 a day but usually about 500 or more sometime nearly 800. And I watch what I eat, my caloric intake is a little on the higher side because of all the weight lifting I do and I do have protein shakes and add protein to my cereal and things like that. I've gained about 2 pounds in the first 2 weeks which is normal when you're gaining muscle but I still feel like my stomach isn't changing. I'm going for a six pack, I feel like I've been working very hard but sometimes I even feel like the fat around my stomach is just getting bigger and I'm frustrated. Am I not doing enough? I do nearly 2 hours 5-6 days a week and I've (in my opinion) drastically changed my diet to a healthier one and watching how much I eat so why do I feel like the exercise isn't paying off? I'm satisfied with the muscle in my arms and legs I can see a difference there but when it comes to the main "core" I'm very unsatisfied. Any ideas on what I can do or what I'm doing wrong? Do I just need to do more?
