• A. Warm-up
• B. Frostbite
• C. Resting heart rate
• D. Progression

Answer: (D)

Progression in exercise programming means gradually increasing the workload over time to stimulate improvements in fitness. By steadily raising the demands placed on the body, you trigger adaptations such as stronger muscles, greater endurance, and improved cardiovascular efficiency, while allowing recovery between increases. A well-planned progression might involve lifting heavier weights, adding more sets or reps, extending session duration, or increasing training frequency in small, attainable steps. This use of gradual overload keeps gains coming and helps prevent plateaus or overtraining.

A warm-up is a preparatory phase at the start of a session to raise temperature and readiness, not a long-term load increase. Frostbite is an injury from cold exposure. Resting heart rate is a measurement of heart function and fitness status, not the concept of increasing workload over time.
