Each set includes four 12" x 18" laminated, full-color posters.Excellent Posters! These posters are great! Laminated to avoid mess, concise exercises, wonderful pictures and explanations. I have them hanging in my work out room on different walls, so I can work on the designated body parts on alternating days, and not have to re-hang the posters as I use them.Weight training posters Bought this for my teens who are just learning how to strength train with light weights. Very easy to follow for them and for me.
