The optimal exercise bike speed for achieving maximum cardiovascular benefits during a workout is typically around 50-85 revolutions per minute (RPM). This range helps to elevate your heart rate and improve cardiovascular fitness effectively.
Using a recumbent trainer for cardiovascular exercise offers benefits such as reduced strain on joints, improved comfort during workouts, and the ability to target specific muscle groups.
Running is cardiovascular exercise, because it increases the rate at which the heart pumps blood through your body to supply your muscles with oxygen during their contractions.

You will be fat.
During exercise, venous return increases due to the contraction of skeletal muscles and increased respiratory rate. This increased venous return leads to higher cardiac output and improved circulation, allowing more oxygen and nutrients to reach the muscles. Overall, this helps to enhance cardiovascular function and improve exercise performance.

You move more, your pulse is faster.
The respiratory system is unimportant during strength training and stretching. It is very important during cardiovascular exercise (cardio). Regular cardio that is neither too mild nor too strenuous can be very beneficial to your body. .
