Question

lea wants to maintain strong bones as she ages. which bone - strengthening activity should she incorporate into her current plan?
running
biking
horse back riding
yoga

Explanation:

Weight - bearing exercises are effective for bone - strengthening as they put stress on bones, stimulating bone growth and maintenance. Running is a weight - bearing activity as the body's weight is supported by the legs and feet while running, and this impact helps strengthen bones. Biking is a non - weight - bearing exercise (the bike supports most of the body's weight), horseback riding has less direct weight - bearing on the bones compared to running, and yoga is more focused on flexibility and balance rather than bone - strengthening through weight - bearing impact.

Answer:

A. running
