im thinking about lifting some weights .. maybe take some steroids 
Lifting weights sounds like a good idea if you want to target certain muscle groups.
yea, but the roids will speed up the process
You can use weighted bars, dumbbells, and weight stacks to use the force of gravity and create muscle through concentric and eccentric contraction! 
yea i guess thats true
What else do you want to know? There are tons of sports that use strength training as part of their training routine, like American football, baseball, lacrosse, hockey, and more.
