I'm starting with cardio most likely next month, but I'll probably go with a jump rope. I might add boxing on some day, though. I'm planning to get ripped till June-July so I'll add whatever I can and ditch some food/alcohol. I just want to get bigger legs now, it's my weakest part because I was not doing them for like one and a half year. I've started recently and at the moment I'm squatting my own weight.
Btw, I never get how people look quite normal (not to say like shit) when their meal plan is the best (great carbs, a lot of protein, healthy fats etc.), when they do cardio and take supplements while they train for many years. I'll never get that.
