Who Should Buy a Kettlebell
Kettlebells are a versatile fitness tool and are used in a variety of workouts. While most workouts involve your arms, there are kettlebell workouts that include the legs and back. They’re an inexpensive and space-conscious way for beginners to get into fitness. Instead of needing to purchase a whole slew of gym equipment, all you need it a kettlebell. Kettlebells also create functional strength. Unlike some exercise tools, many kettlebell exercises help you get stronger at every-day movements, like lifting or swinging things. You’ll see a noticeable strength difference in your everyday life when you train with a kettlebell, while you won’t necessarily see such a difference with other workout equipment.
Those who are just getting into fitness and experts who are looking to shake things up will likely benefit from a kettlebell. These easy-to-use tools are versatile and can help you work out all parts of your body at once. They’re wonderful for those with time constraints, as they let you shove cardio and weight exercises into one routine.
After your workout with your adjustable kettlebells, you may find yourself hurting. If you’ve pushed yourself and are in need of a way to ease that discomfort, be sure to check out How To Relieve Sore Muscles After A Workout.
Important Features to Consider
A kettlebell should have a few important features. Here’s what to consider when purchasing a kettlebell for your exercise routine:
- Durability. Kettlebells are used in some rough exercises. They’re slung around, set down, and occasionally rammed into things. In order to keep up with this tough routine, any kettlebell you choose needs to be durable. The most durable kettlebells are made with cast-iron. This material is both durable and heavy, which is useful if you’re trying to squeeze more weight into the small fitness tools. Types of metal can also work well and are typically used for less expensive kettlebells. Metal won’t be as heavy as cast iron and isn’t quite as durable, but it can be a decent, cheaper material.
- Adjustability. An adjustable kettlebell should have a wide range of adjustability and be easily adjusted. A kettlebell is not going to do you much good if you have to spend twenty minutes to adjust it by five pounds. A kettlebell should preferably only take a few moments to adjust and should be able to accommodate a large range of weights. If you’re a beginner, be sure any kettlebell you choose goes down to a low enough weight. Many start a little high and are not quite suitable for those starting to get into fitness.
- Included weights and plates. Some adjustable kettlebells come with weights or plates. If weights are included, you will not have to purchase weights separately or use the standard weights at the gym. These tend to be a little more expensive, but the included weights mean that you can start using the adjustable kettlebell immediately. On the other hand, some kettlebells come with plates, which are weightless but work a place-savers for weights. These plates can make your kettlebell more balanced if you aren’t putting tons of weight on it.
- Comfort. Not all kettlebells come with comfortable handles. Be sure whatever kettlebell you purchase has a large enough handle for you to grip comfortably with two hands. Otherwise, you might have difficulty doing certain workouts.
- Warranty. Most kettlebells come with a warranty of some sort, but it is a good idea to check before you make a purchase. It is nice knowing that if a kettlebell doesn’t work out for you, you can get your money back.
