NOFFS Sandbag is the fourth program in the Navy Operational Fitness and Fueling System (NOFFS) series, developed by the Navy in partnership with EXOS. This lifestyle and health & fitness app is designed to provide Navy Sailors and health professionals with a world-class training resource.

The NOFFS program incorporates sports science methodologies to combine human performance and injury prevention strategies. It focuses on exercises that replicate the activities Sailors perform in their operational duties, such as lifting, pushing, pulling, and carrying. The program also includes fueling strategies to determine caloric needs based on personal goals, a meal builder to choose high-octane foods, and a regeneration component to address aches and pains.

The Sandbag Series, an advanced program within NOFFS, offers a training plan that can be performed in environments with limited equipment options. By using a sand-filled bag, it provides a unique training experience that mimics the demands of day-to-day life. The series progresses through three phases, building upon previous work and preparing for higher performance demands.

Overall, NOFFS Sandbag is a comprehensive fitness program that focuses on strength, power, and mobility, making it an ideal resource for Navy Sailors looking to enhance their physical performance in operational environments.
