Exercises that improve both cardiovascular endurance and strength include activities such as running, cycling, and swimming, which boost heart health while also engaging various muscle groups. Incorporating resistance training—like weightlifting or bodyweight exercises—can further enhance muscular strength. High-intensity interval training (HIIT) is particularly effective, as it combines short bursts of intense activity with recovery periods, optimizing cardiovascular endurance while building strength. Balancing these exercise types in a routine fosters comprehensive fitness and can lead to improved overall health and performance.
