For body composition, how many days per week should cardiovascular training be performed?

• A. 1-2x a week
• B. 4-6x a week
• C. 7x a week
• D. 2-3x a week

Answer: (B)

To change body composition, you need enough weekly cardio volume to create a solid energy deficit while still allowing time for recovery and resistance training. Doing cardio multiple days per week provides consistent calorie burn and metabolic benefits, helping fat loss without sacrificing muscle when paired with strength work and adequate protein.

Four to six sessions weekly hits a practical balance: it gives enough total minutes of cardio to drive meaningful fat loss, yet leaves days for lifting and rest so recovery and performance aren’t compromised. Doing cardio only 1–2 days a week usually doesn’t add up to enough total energy expenditure for noticeable changes. Training every day can be excessive for many people and may hinder recovery, especially if intensity is high. Two to three days per week offers some fat-loss benefits but generally isn’t as effective as higher-frequency cardio for maximizing body recomposition.

In short, four to six days per week is the most effective range for improving body composition through cardio, with a mix of moderate and optional higher-intensity sessions to fit individual goals and recovery.
