I'm not fat by any means, but I have noticed that most of my clothes, from the start of working out, don't fit anymore. Based on my progress log, I'm feeling that maybe I should include more cardio into my routine? Can someone please give me a cutting routine for 4 days or point me in the right direction? Or recommend what I should do to keep from becoming more bulky as my body tends to do.
Any help is greatly appreciated!
