Functional training is a type of training that aims to improve your performance in everyday activities, sports, or other physical challenges. It focuses on developing strength, mobility, stability, endurance, and power in a holistic and integrated way. Kettlebell flows and complexes are great for functional training because they engage multiple muscle groups and joints at once, mimicking real-life movements and scenarios. Additionally, these exercises can enhance your cardiovascular fitness, metabolic conditioning, and calorie burning as you keep moving without rest. Furthermore, kettlebell flows and complexes can improve your coordination, balance, and agility as you switch from one exercise to another and control the kettlebell in different planes of motion. Finally, these exercises can increase your mental focus, concentration, and awareness as you have to pay attention to your form, breathing, and timing.
