Blue-red stripes after training, also known as petechiae, are caused by tiny blood vessels bursting under the skin due to intense physical activity or pressure. This can happen when there is increased pressure on the capillaries, such as during weightlifting or intense exercise. The burst blood vessels result in the appearance of blue-red stripes on the skin, which typically fade within a few days as the body reabsorbs the blood. It is important to ensure proper form and technique during exercise to minimize the risk of developing petechiae. **

Blue-red stripes after exercising, also known as exercise-induced vasculitis, are caused by inflammation of the blood vessels due to increased blood flow and pressure during physical activity.

This condition is usually harmless and resolves on its own, but it is important to stay hydrated and properly cool down after exercising to help prevent it. **

Additionally, certain medications or medical conditions that affect the skin's elasticity can also contribute to the development of blue stripes on the thighs. **
