Question

1. which activity is best known for building bone strength and long-term mobility?

a. strength training

b. aerobic exercise

c. stretching

d. yoga

Explanation:

To determine the activity best for building bone strength and long - term mobility, we analyze each option:

• Option a: Strength training (such as weight - lifting) places stress on bones. This stress stimulates bone growth and increases bone density, which is crucial for bone strength. It also helps in maintaining muscle mass around the bones, which supports long - term mobility.
• Option b: Aerobic exercise (like running, cycling) is mainly focused on improving cardiovascular health, endurance, and burning calories. While it has some overall health benefits, it is not the primary activity for building bone strength.
• Option c: Stretching is mainly used to improve flexibility, range of motion of joints, and reduce muscle tension. It does not have a significant impact on bone strength.
• Option d: Yoga is good for flexibility, balance, and mental well - being. But it is not the most effective activity for building bone strength compared to strength training.

Answer:

a. Strength training
