Kettlebells are a type of home workout equipment that people may use for strength training exercises. They are dome-shaped and typically have a handle attached to the top.
Standard kettlebells have a fixed weight and come in varying sizes. In contrast, an adjustable kettlebell is a single piece of exercise equipment that a person can add or remove weight from as desired. These kettlebells feature a leakproof bag, so individuals may add water, sand, or gravel to adjust their kettlebell’s weight.
Adjustable kettlebells are generally more cost-effective than buying sets of kettlebells. They may also suit individuals with limited space for exercise.
People can perform the same exercises with standard and adjustable kettlebells. Some of these include:
- kettlebell swings
- goblet squats
- sumo upright rows
- Russian twists
Individuals may wish to consider the following kettlebell features before making a purchase:
- Handle: Kettlebells with a wide handle may suit taller individuals or those with larger hands. They may also suit people who wish to perform exercises involving holding a kettlebell with both hands.
- Size: Adjustable kettlebells, especially those that require sand or water for adding weight, are larger than traditional variants. With this in mind, a person may prefer more space-saving exercise products.
- Weight: Beginners may buy kettlebells that come with weights ranging between 5 and 10 pounds (lb). Those who exercise regularly may prefer a kettlebell with 30–40 lb of weight.
