Hi I am 28 years old and I have not worked out sense highschool, people often mistake me for being 15 some times I am just small. I want to work out and get bigger and look more well my age. What i am worried about is that, sense ive not done any kind of work out for over 10 years now how hard should i start out. I am really weak looking and, I feel it to and i am not sure if I start out if it is possible i can over do it and hurt my body. I gota increase my eating more to I have been told, any advise anyone can give me on how to start out would be greatful thanks for reading have a great day.
