Stop all the cardio. Right away. That much cardio is unecessary, and as your body is trying to tell you, you are overdoing it BIG TIME. Your body is probably chuck full of Cortisone at this point!
After you quit it, I think you should rest and "refit" your body by eating Primally. Above all, dont stress about not doing cardio. Take a couple of weeks off to relax and rehabilitate your body and focus on learning & living the Primal lifestyle.It is one of NO STRESS. Especially not over doing cardio six days a week for two hours a day!
After you get to the point where you are relaxed...then I say you can go for a resistance (weight training) work out regimen. But again, DONT BE REGIMENTED ABOUT HOW MUCH AND HOW OFTEN YOU ARE DOING IT! There isnt a formula for how much and how often that works for everyone. Everyone is different. Above all, listen to your body. It will tell you how often you should lift. And if you are in doubt whether you should or not...DONT. With weight training, you grow muscle when you aren't stressed, when you eat properly, and when you rest. NOT WHEN YOU LIFT! Lifting breaks muscle down and if you attempt to do a weight training program like the chronic cardio you were doing...you will SURELY have a breakdown with or without an injury. I promise you. Overtraining on a weight training program is one of the most common mistakes made by beginners.
Anyway, those are my two cents. Whatever advice you end up following...I'd be sure it included getting rid of 6 days per week of cardio for 2 hours per day!!!!
If you can just get your....mind together....then come on across to me.....
