If you’re in a hurry to build big arms, you’re going to need the right tool. Dumbbells are one of the best tools that you can use since they’re easy to find at the local sporting goods store, craigslist or a neighborhood garage sale.
Take care of your dumbbells and they will become your second best friend next to your dog.
Make sure that you use a pair that are heavy enough but not so heavy that you sacrifice form.
Always warm up before jumping right into a biceps/triceps workout.
