Buying a set of dumbbells is a very inexpensive way to starting building up your fitness equipment collection. And your arms. They do not take up a lot of space, and given the right variety of weights, you can use them throughout your entire fitness evolution.
Generally most fitness equipment you purchase will be expensive, because a lot of fitness equipment is made to stand the test of time and last a long time. The fitness equipment has to be sturdy enough to survive a drop in case your grandma tries lifting it and fails, and it has to be unbreakable so you can push yourself without ruining your fitness equipment. Dumbbells, while they are sturdy and last a long time, are not as expensive as most other fitness equipment. You get all the perks of a long-lasting piece of fitness equipment without spending all of your money!
Once you have your dumbbells, make them work for you! Sure, you will be the one doing the curling and the lifting and the sweating, but your dumbbells will be working just as hard! Every curl you do, your dumbbell will be working for you to give you all the benefits of a curl PLUS that extra kick to challenge your muscles into GROWING. If your arms could challenge themselves without a dumbbell, think of how many people would have GREAT ARMS. A lot! But unfortunately that is not how real life works. Luckily, dumbells love working for us, and get us those results we want but cannot get on our own! Thank you, dumbbells!
Finally, make sure you treat your dumbbells right. They may be sturdy and last a long time, but when you make your dumbbells work for you all day every day, you need to make sure you’re taking good care of them. Wipe down your dumbbells so there isn’t any lingering sweat, and keep them in a safe place where cats or dogs won’t be tempted to make the dumbbells work for them. It just doesn’t work like that when you have claws!
