How do I help keep my skateboard lasting longer?

I am about to get a Plan B skateboard and i know, no matter what you do that skateboards will eventually snap. I am a little on the heavy side around 175 and I was wandering if there is anything that could help reinforce my skateboard to help prevent snapping of my skateboard? Any ideas help! Home remedies, store bought items, anything! I just need some help! Thank you!
