when u flex it, it tightens, when u extend it, it stretches

Flexion is when a muscle action decreases the angle at a joint, extension is when the angle increases. A simple example is bicep curl, flexion is when the hand is brought up towards the shoulder, decreasing the angle at the elbow joint. Just because a muscle is performing flexion or extension does not not mean it is contracting or stretching, that is eccentric and concentric movement. A muscle can still be tight when performing extension.
