How can you skateboard in good condition? I read somewhere you do not lubricate the bearings, but how do you do it.

I get Plan B skateboard, and I know it does not matter what you do, such as skateboards end easily. I am a bit heavy side, about 175 and was wandering if there is anything that can help strengthen my skateboard to stop snapping my skateboard? All ideas will help! Home Remedies, bought some store items! I need help! Thanks!
