The kettlebell may just be a simple ball of iron, but its benefits shouldn't be underestimated. A workout with a single kettlebell can help you burn a ton of calories, build strength, and boost muscle growth (to name a few), and that's exactly what this workout intends to do. Get ready to blast your way through this full-body workout in just 20 minutes.
As well as making strength and muscle gains, kettlebells are a great tool for building a rock-solid core. Despite not directly targeting the midsection muscles (like you may do with crunches) most kettlebell exercises work your body through different ranges of motion. This challenges your stability, therefore requiring your core to work harder. Not to forget, by using a single kettlebell and performing unilateral exercises on one side of your body, your core will light up as it tries to remain steady and resist the weight from the other side.
