This work has pictures showing and naming the exact muscles engaged by 115 exercises, so you can see the difference between, say, a bicep machine curl, a preacher curl, a barbell curl, and a hammer curl. Each exercise also has a short description and a couple diagrams of the movement. The book covers all areas: arms, shoulders, chest, back, legs, butt, and abs. A few extra articles cover joint and injury issues.
