Question

which of the following is an example of cross training?
a professional biker lifting weights to strengthen thigh muscles
a sprinter practicing race starts from the starting blocks
a swimmer practicing different swimming strokes

Explanation:

Cross - training involves using different types of physical activities to improve performance in a particular sport. A professional biker lifting weights to strengthen thigh muscles is an example of cross - training. This is because the biker is using weight - lifting (a different activity than biking) to enhance a specific aspect (thigh muscle strength) relevant to their sport. A swimmer practicing different swimming strokes is just refining skills within the same sport (swimming), and a sprinter practicing race starts from the starting blocks is also focused on improving skills within the sprinting discipline.
