I know cardio is optional, I'm currenly eating:
2140 calories
175g protein
180g carbs
70g fat
Working out 5 times a week with a 50 calorie warm-up on treadmill.
I'm 5"11 170lb 13%bf trying to get to 9% body fat without losing muscle. I am losing 1lb a week but I'm not getting much more vascular and my muscles don't seem hard. Would doing cardio make a SIGNIFICANT difference or is it really just the simple math explanation. If i burn 100 calories running daily, that's 700 a week, that's about 1lb a month and nothing more to it?
Thanks.
