Adoctor has told frida she must engage in physical activities to improve her heart health and minimize the chance of injury. which of the following is best for her to try? dancing sit-ups pull-ups karate

The correct answer would be dancing.

Dancing is a low to medium impact physical exercise that does not put that much pressure on the body, it is as fun activity and would help with Frida's cardiovascular system as it will get her heart beating faster and her blood pumping but with much less risk than a higher impact activity such as Karate. She could put herself as risk of injury from doing Karate, sit-ups and pull-ups.
