    “Muscle size” refers to the goal of muscle mass gain (or hypertrophy), which occurs primarily as a result of an increase in the size and/or number of myofibrils (i.e., bundles of protein filaments within muscle fibers that produce muscle contraction).[1] “Muscle strength” refers to the ability to produce force against an external resistance.[2]
