How Muscles Grow After Workouts

This shows what happens to your muscles before, during, and after a workout.

Most people think lifting weights builds muscle—but it actually does the opposite.

Training creates tiny tears and damage in your muscle fibers while also triggering new myofiber formation,

which are separate processes. Protein provides the raw materials for repair and growth,

but without enough recovery, nothing happens. Your muscles need about 48 hours before

being trained again. If you want real progress, lock in your nutrition and give your muscles

the time they need to grow bigger and stronger.
