The biggest difference between masters of external and internal arts is probably Inner Strength.
Masters of the internal arts channel their energy into their abdomen, relying on their profound Inner Strength to unleash latent power within their bodies, displaying remarkable prowess. It's challenging to get started, the rate of progress in strength is usually moderate, but the bottleneck period tends to occur later.
On the other hand, masters of the external arts have Inner Strength on the surface, extremely firm and vigorous; while the physical body is crucial, Inner Strength is also a key component. It's easy to get started, and their strength increases rapidly in the initial stages, mostly relying on the body-strengthening effects of medicinal baths.
