whole body. Don't Let your self down, keep working to be the best. A little work out is okay, you're at least doing it and when you workout you get benefits from it you get healthier and most illnesses come from fat so come on just one step at a time.
When I have kids I'm going to get them in the habit of working out because I hate how difficult it is to start after not doing it for 2 years & bullshitting in pe during the years i had the class at school. I'm I'm too young to feel like this.
