                                Over 90% of the body's stored energy is in the form of triglycerides within adipose tissue, but a significant and readily accessible portion is also stored directly within muscle fibers. This fuel depot, known as intramuscular triglycerides (IMTGs), is a crucial energy source during prolonged exercise, with its usage varying based on exercise intensity, duration, and an individual's training status.
