Verified step by step guidance

Understand the concept of bone strength: Bone strength is influenced by activities that apply stress to the bones, stimulating bone remodeling and increasing bone density.
Identify the types of exercises: The options provided include swimming, weight-bearing exercises (e.g., running or jumping), stretching exercises (e.g., yoga), and cycling.
Analyze the impact of each exercise type: Swimming and cycling are low-impact activities that do not place significant stress on bones. Stretching exercises like yoga improve flexibility but do not directly contribute to bone density. Weight-bearing exercises, however, involve activities where bones support the body's weight against gravity, stimulating bone growth.
Connect the concept to the correct answer: Weight-bearing exercises, such as running or jumping, are most effective for building strong bones because they apply mechanical stress that promotes bone remodeling and density.
Conclude: The correct answer is weight-bearing exercises, as they directly contribute to bone strength by stimulating bone-forming cells (osteoblasts) through mechanical stress.
