Which modification is recommended for cardiovascular activities for beginners?

• A. Jogging at sprint pace
• B. Swimming without flotation devices
• C. Avoid intervals altogether
• D. Jogging as brisk or power walking with intervals to progress

Answer: (D)

The key idea is to build cardio gradually by using a manageable effort and built-in recovery. For beginners, starting with a pace that lets you talk in sentences and adding structured intervals lets you control how hard you work while giving your body time to adapt. Jogging at sprint pace is too demanding at first and can lead to early fatigue or injury. Swimming without flotation devices assumes a certain skill level in the water and isn’t a universal progression method for beginners. Avoiding intervals altogether misses a practical way to progressively increase workload safely. Mixing brisk jogging or power walking with planned intervals provides a sustainable path to higher endurance by gradually increasing effort and allowing recovery between efforts.
