Which physical activity is NOT aerobic exercise?

• A. Hip-hop dancing
• B. Jogging
• C. Jump roping
• D. Yoga

Answer: (D)

Aerobic exercise is sustained, rhythmic activity using large muscle groups that raises heart rate and relies on oxygen to meet the body's energy needs over time. Activities like hip-hop dancing, jogging, and jump roping fit this pattern because they can be kept up for several minutes at a pace that keeps the heart rate elevated. Yoga, on the other hand, is typically focused on flexibility, balance, and strength with shorter periods of sustained movement and generally lower heart rates. It’s not designed to maximize cardiovascular endurance in the same way as the other activities, so it’s not considered aerobic.
