How can juggling benefit your coordination and cardiovascular fitness simultaneously?

Juggling is often perceived as a circus trick or a fun pastime, but it has intriguing benefits for physical fitness. This question explores how the seemingly simple act of keeping multiple objects in the air can enhance both coordination and cardiovascular endurance. Juggling demands precise hand-eye coordination and keeps your reflexes sharp as you track and adjust for each object's path. At the same time, when practiced for extended periods, juggling can serve as a moderate aerobic exercise, increasing heart rate and thereby benefiting cardiovascular health. How does this dual benefit of juggling compare to more conventional exercises, and could it serve as an efficient alternative for those aiming to improve both their coordination and cardiovascular fitness?
