In the FITT framework for body composition, what is the typical session duration?

• A. 20-30 minutes
• B. 30-45 minutes
• C. 45-60 minutes
• D. 60-75 minutes

Answer: (B)

Time in FITT refers to how long a single training session lasts. For body composition goals, about 30 to 45 minutes per session is the typical duration because it provides enough training volume—enough sets, reps, and chosen intensity—to stimulate changes in muscle and fat without creating excessive fatigue that can hurt technique or make workouts hard to maintain. Shorter sessions (20–30 minutes) may work for beginners or highly efficient routines, but they often miss enough volume for noticeable changes unless done very frequently. Longer sessions (60–75 minutes) can be useful for advanced programs or higher weekly volume, but many people struggle with adherence. So, 30–45 minutes is the common default that balances effective stimulus with practicality.
