Help with workout - what i should be doing different?

[retired_mike579uk]

i just bought a olympic weight bench so i could start benching ...
I run atleast 5 days a week ...
just started doing some crunches ...
dips
some curls
and always have done push-ups ...

my main concern is .... i'm i waisted my time on push-ups or do they actually work out different parts then then benching ...

also my back arm is already well-defined but my biceps aren't ...
should i catch up on them to have a complete muscular arm ... ???

thanks for the help!

I say always keep doing pushups, its good to use bodyweight exercises.
Do you work your back? Do you work your Legs (excluding Running).

What is your main goal?
