Why do muscles fatigue?

What causes muscle fatigue during exercise?

Why do my muscles get so sore after workout?

During these contractions, other muscles will contract isometrically to provide stability. As your muscles adapt to the activity, lactate levels increase, and microscopic damage to the muscle fibers and connective tissue takes place. The soreness you feel after a workout is caused by your muscles naturally learning and responding to a new activity.
