What role does No. 7 Rage aim to fulfill during exercise?

No. 7 Rage is designed to amplify blood and nutrient flow to muscles during exercise, primarily through its effects on nitric oxide production. This enhanced blood flow helps deliver more oxygen and essential nutrients to working muscles, which can improve performance, delay fatigue, and support recovery. By increasing vascularity and nutrient transport, it allows for a more effective workout session and can lead to better gains in strength and muscle development.

The other options, while relevant to different aspects of fitness, do not specifically describe the primary function of No. 7 Rage. Enhancing endurance focuses on stamina over prolonged periods, providing weight gain support targets muscle mass increase rather than performance during a workout, and improving flexibility pertains to the range of motion rather than nutrient delivery. Thus, the emphasis on blood and nutrient flow is what sets No. 7 Rage apart in its intended role during exercise.
