Interval training involves which pattern?

• A. Training with weights.
• B. Alternating work and rest periods.
• C. Only sprinting.
• D. Continuous low intensity.

Answer: (B)

Interval training is defined by alternating bouts of higher-intensity work with periods of rest or low-intensity recovery. This pattern—hard effort followed by recovery, repeated several times—is what makes interval training distinct and effective for boosting speed, endurance, and cardiovascular efficiency.

Training with weights targets muscular strength and power through resistance, not the repeated push-rest cycle of aerobic work. Only sprinting describes a brief high-intensity effort, but interval training isn’t limited to sprinting; it uses varying work and rest intervals with different intensities. Continuous low intensity describes steady-state cardio, where you maintain a steady pace without built-in recovery bouts.
