Which strategy is least effective in preparation for the CFT?

Focusing only on cardio without strength training is least effective for preparing for the Combat Fitness Test (CFT) because the CFT evaluates multiple physical fitness components, including strength, endurance, and agility. While cardiovascular endurance is essential, the test requires a balanced approach to fitness that includes strength training to improve overall performance. Relying solely on cardio can leave significant gaps in strength and functional fitness, making it difficult to excel in the various components of the CFT, such as the movement to contact and ammunition can lifts, which require a combination of strength and endurance. A comprehensive training regimen that includes both cardio and strength training is essential for optimal performance in the CFT.
