Devon has not seen improvement in his cardiovascular fitness goal. What goal adjustment should he employ to improve?

Increasing the speed of exercise can be an effective way to enhance cardiovascular fitness because it directly influences the intensity of the workout. When a person exercises at a higher speed, their heart rate increases, leading to greater cardiovascular demand and, consequently, improved cardiovascular fitness over time. This adjustment can challenge the body to adapt and strengthen the heart and lungs, promoting better endurance and fitness levels.

Adjusting the speed can also make workouts more engaging and varied, which may help maintain motivation and consistency in training. This is crucial for achieving fitness goals, especially if previous routines have stagnated in terms of progress. By incorporating speed into workouts, Devon can effectively stimulate improvements in his cardiovascular fitness.
