Kettlebells are an excellent way to increase core strength and target muscles that dumbbells and barbells can’t reach. They consist of a bell, handle, and “horns”. They are harder to control than dumbbells, thus incorporating more core strength, stricter form, and more muscle activation.
Kettlebells encourage precision, because you can more easily tell when a part of the exercise is off. These pave the way to perform more advanced exercises properly. When you train with a kettlebell, your core has to work harder to stabilize the weight and this builds improved athleticism.
Kettlebells are easy to travel with as they won’t roll around your car. You only need a single kettlebell for a good workout, not a selection, so they are a great first addition to an at-home gym.
