RED-S occurs when the body doesn’t get enough energy over a long period — meaning it doesn’t take in enough calories from food to cover both training demands and basic daily functions.
When the body lacks energy, it starts saving where it “can” — for example, healing slows down, hormonal balance is disrupted, immunity weakens, sleep quality drops, mental well-being suffers, and sports performance declines.
A partial biceps rupture may not appear dramatic at first glance, but without proper management, it can lead to long-term functional limitations in the upper limb. This injury refers to an incomplete tear of muscle or tendon fibers, most commonly involving the long head of the biceps tendon, which plays a key role in elbow flexion and forearm supination.
Multiple sclerosis (MS) is a condition that affects the central nervous system — the brain and spinal cord. It can cause a wide range of symptoms, including fatigue, balance problems, numbness, and difficulty walking. Many people living with MS gradually find it harder to move, often feeling unsteady or weak in their legs. This can lead to them avoiding movement and spending more time indoors.
