Why do our muscles get bigger after strength training?
Human bodyMuscle
Quick Answer
Strength training causes tiny stresses in muscle fibers, and the body repairs them by making the fibers thicker and stronger. This adaptation is called hypertrophy.
The Full Story
Resistance exercise creates microscopic damage and high mechanical tension in muscle fibers. In response, the body activates protein-building pathways that repair and reinforce the fibers, especially when enough food and recovery time are available. Over time, the muscle cells increase in size and their supporting structures become more robust. The nervous system also improves coordination, so strength gains are not from muscle size alone.
Key Facts
1.Muscle growth from training is called hypertrophy
2.Repair after microscopic damage builds thicker fibers
3.Strength gains also come from nervous system adaptation
