I am currently 5'11" weighing about 140 lbs. Obviously, I'm fairly skinny but I have enough muscle for some definition in the abs and shoulders. I run on occasion to keep my body fat down, but usually not more than a few miles a week. I do a decent number of crunches, calf raises, and some pushups. I'm a musician, and I find that any intense exercise of my arms makes me lose my fine coordination for a couple days which makes it difficult to play. Basically, I would like to be fit, maybe somewhat toned, without being bulky. I find myself falling behind in soccer games with friends and I get out of breath fairly quickly. The vast majority of my body fat is located in my lower body, but there is a smaller layer over my abs and arms that I would like to cut down as well.
So, do I basically just want to start running more often? Is there any specific way I should go about it, because right now I just go for a light jog of a mile or two a couple times a week. I eat a lot of carbs so I probably want to cut back on those as well. Is there anything else that I should watch in my diet? I'm a vegetarian (that includes fish) and really do not enjoy plain eggs, so getting enough protein is tricky. Also, could you recommend exercises I could do in or around the house (I want to avoid having to purchase a gym membership). Looking back on it, it's a miracle that I'm not fat and that I have any muscle at all.
I know I'm not giving you much to work with. Feel free to ask for any more info. Thanks!
