Question

Paul's doctor says his cardio respiratory fitness level is excellent, but she worries about Paul's muscular fitness. Paul enjoys gymnastics, baseball, biking, and yoga. Increasing the frequency of which activity will best improve Paul's muscular fitness?

Answer 1

The correct answer should be gymnastics. While the other mentioned sports could help him too, gymnastics is the most comprehensive one because it involves almost every muscle in the body to do various exercises, whereas biking would increase his leg muscle fitness most, but would not do much for the rest of his body.
