Muscles are composed of muscle fibres which are themselves composed of myofibrils, which are the contractile units of your muscles. During a workout, these fibres activate: the muscle shortens, creating a muscle contraction, causing the ends to draw closer together, and thus causing movement.
What happens to your muscles during exercise?
More blood is pumped to the exercising muscles to deliver that additional O. Without enough oxygen, lactic acid will form instead. Lactic acid is typically flushed from the body within 30 to 60 minutes after finishing up a workout. Tiny tears form in the muscles that help them grow bigger and stronger as they heal.
What do your muscles need during exercise?

What happens to veins during exercise?

Why do muscles need more blood when exercising?
When the muscles start to work, they need more oxygen so the respiratory system responds by getting more oxygen into the lungs. The blood carries greater amounts of oxygen and the heart responds to pump more oxygenated blood around the body. After exercising, the muscles need to rest, adapt and recover.
