You Can't Build "More" Muscle
Here's something I find very interesting.
Most of us know that "hypertrophy" relates to the enlargement of muscles due to exercise. But did you know that muscle cells can only grow in size and not quantity, as muscle fibres are incapable of reproducing through mitosis, or cell division?
This means that the only way to "build muscle" is to enlarge the muscle fibres you already have, and it is basically impossible to create "new muscle"
I guess this also means that prime Arnold technical may not have had more muscle than me, his muscles are just bigger.... lending credence to the ol' adage "size matters" 😂
