In many ways, dumbbells are much better than barbells. It allows you to target the muscles in a particular arm. This helps a lot if you’re a tennis player, since your dominant arm will be more stressed and you’ll need to focus more on your other arm to balance this up.
In addition, you don’t need as much space to use dumbbells. They’re also safer, since you don’t need a spotter to keep you from getting crushed. Using barbells without a spotter can be dangerous, or you will have to spend more money on a power rack.
However, getting fixed-weight dumbbells can be problematic as well. You will need a lot of them so that you can progress and use different weights in your workout. However, you can opt to use adjustable dumbbells instead. A single pair of dumbbells can take the place of 16 or more separate dumbbells.
The best adjustable dumbbells offer a range of weight that’s right for your strength and skill level. The weight changes should allow for small incremental change as well. It should be easy to adjust the weight, and the metal plates should be secure in their place. The handle should be comfortable, and the dumbbells should last for a long time.
