Ditto what Swanso said.
And I agree with Clare...You are doing WAY TOO MUCH CARDIO and not enough free weights. You will never gain the muscle you want by burning it off with that amount of cardio and from personal experience, you are doing more harm than good. I will admit that when I began getting serious about taking care of body I did exactly what you are doing. And only excuse is lack of knowledge and experience. Use the resources that are available to you. After research of own, the help from the wonderful people on this site and hiring a personal trainer, I have learned a lot. Your body needs rest just as much as it needs a good, quality workout with proper form and equally clean, well balanced nutritional diet.
Remember when you lift weights, proper form is crucial, if you find yourself rushing to get through the set because the weight is too much, you risk injury and once again are wasting your time. Stop that set immediately, drop your weight and work on form. Once you have it mastered, then increase the weight. Pay attention to each exercise you perform and concentrate and what muscle groups you are training. It takes a little practice, but once you get into this habit it will come natural to you as you progress.
As far as your cardio goes, I have no issues with endurance exercise, as I once trained for a triathlon with SarahPT from this site and upping endurance is what I needed to do to compete. But from what I understand, you want to gain muscle mass. Once again, and only speaking from experience, think about doing HIIT 2-3 times a week for approximately 15-20 minutes rather than than endurance types (60 minutes of cardio). You'll burn more fat (which is what you claim you want to achieve) and you may yield better results. When you research HIIT, as you read it it seems easy, once you perform it properly, it will kick your and you will feel like you kickboxed or cycled for an hour.
I'll be the first to admit, I feel better when I get a good sweat in for a long period of time after running or cycling for an hour, and there are some weeks I do just that. Usually it's to relieve stress, and it works! But I don't do it every week.
Good luck with your endeavors and keep us posted
A little scared, I hope I don't injure myself. When I ran a half marathon last summer, ankle was in pain for a couple of months. Anywho, time to go out!!!
