Im 19 yrs old. I do manual labor all day so i lift a good bit.. I havnt lifted weights ever seriously but i do do pushups and pull ups daily every change i get til i cant feel my arms.. stretches etc.. and eat descent. I drink protein shakes as well. I am looking to gain some mass but mainly strength.. like i said i dont use weights yet.. but it'll only be dumbells or w/e.. i cant afford a membership to gyms or buy a home workout station. Call me dumb, but one of my friends told me to buy omnevol and i did.. before i researched it and everyone seems to run the other way about it.. Any tips would be awesome! thanks.
