The word “kettlebell” first appeared in a Russian dictionary in the early 1700s, but history shows that kettlebell-like weights had been utilized centuries before that by the ancient Romans and Greeks. By the late 1940s, modern Kettlebell Lifting had become Russia’s national sport. They’re oddly shaped workout tools, but their popularity continued to spread throughout the world because of their ability to work multiple muscles and provide a total-body workout in a short period of time.

SPRI’s kettlebells and kettleballs are sleek, updated versions of the traditional tools. As novice users progress, they can choose products with a different size and weight distribution. All users, from beginners to advanced participants who want to perform more-complex moves, can find the right product to meet their needs.

Kettlebells and kettleballs are training tools that fall in the weighted-resistance category, which means they are used to help increase explosive power; improve endurance, grip, and mobility; and enhance muscle strength. Products in this fitness category are built to withstand tough training conditions, since they get pretty beat up during rigorous use.

Kettlebells come in color-coded weights ranging from 5 pounds to 50 pounds, and kettleballs come in weights ranging from 5 pounds to 35 pounds.

Q: I’ve never used kettlebells before. What benefits can I expect from working out with them?
A: Beginning users who train with kettlebells or kettleballs can start to build muscle stamina; improve grip strength; increase body awareness and joint integrity; learn proper breathing and stabilization; and start to increase heart and lung capacity. As you improve, you can move up to higher-weight kettlebells and further increase muscle definition, strength, and coordination.

Q: I’ve trained with kettlebells for years. Am I still reaping the benefits?
A: Yes, even after working out with kettlebells or kettleballs for a long time, the user is benefitting from training—just as you would if you were talking about dumbbells or barbells. As advanced users move up to higher weights, you’re continuing to increase muscle size; enhance force production and force absorption; and master full utilization and coordination of upper-extremity mobility and stabilization, core and pelvic activation, along with hip, glute, and thigh explosiveness.

Q: Does the size of the bell portion matter?
A: Yes, the size of the bell portion of a kettlebell or kettlebell helps determine how advanced the movements may be. The bell size can be larger for less-advanced movements, but should be smaller for more-advanced ones.

Q: I tried a kettlebell at my gym but it was hard for me to grasp. Are SPRI’s kettlebells easier to hold?
A: Yes, all of SPRI’s kettlebells and kettleballs are comfortable to grip because they are generously sized with a curved-horn shape.

Q: What’s the difference between kettlebells and kettleballs?
A: Kettlebells and kettleballs provide the same benefits during workouts, but there are slight differences. Kettlebells vary in size depending on the weight, while kettleballs are all the same size, regardless of weight. Both kettlebells and kettleballs are color-coded by weight and both have soft coverings to protect floors. They also have a flat bottom so that they stay put on the floor without rolling away. (Traditional exposed-metal kettlebells, however, require a protective floor covering to prevent damage.)
