I'm a beginner who is at 223 lbs. I'm doing 3 workouts a week (pushups, pullups, crunches, squats/lunges) I do cardio exercise 2 times a week (jogging, swimming, bicycling, etc.) Then I rest on weekends.

My question is:
Addition to my workout/cardio schedule, I like to walk everyday for at least 30 mins to 3 hours. Low carb is giving me tremendous amount of energy to work with. Is this a bad idea because I'm not giving my body time to rest? Or is walking this much okay because its not as intense?
