hi ciaran,
actually, bench presses are a very good compound exercise. its one of the main compound lifts. youve also got squats and deadlifts. though take it from me, i used to do quite a bit of body building, muscle mass just gets in the way if you want to dance. For me, i prefer now to do isometric exercises, and generally any kind of exercises that use the body weight for resistance. these are good for building strenght and muscle density without a lot of bulk.
so think, pushups, chin ups, the plank, sit ups, leg raises, dips and if you like torture, 1 handed pressups. also pilates and yoga type exercises. just be sure to do them with strict form to exhaustion, rather than aiming for a big number. remember, anyone can do 20 push ups wrong, but very few people can 20 do strict form nose to the floor on your knuckles pushups.
stretching is vital, especially the legs, you dont want to get tight legs, this can result in lower back pain, or worse... a torn hammy.
