Hypertrophy
Hypertrophy means an increase in muscle size.
Hypertrophy: a practical example
For example, a training program may organize exercises and sets with muscle growth as its main goal.
Use it in your log
When you log your workout, keep this in mind: more lifted weight in one workout does not directly measure a change in muscle size.
Next, use the workout log to keep names, weights and reps in one place. Then check your progress across sessions.
