One of the most riveting moments in The Silmarillion for me. I've always seen this as being a feat of spirit or maybe "magic" rather than strength, but I'll admit that brutish muscle is a much simpler explanation. Put Turin or Fingolfin in the same situation and with the same wording, and I'd probably view it the same as you, so it may just be my preconception of Finrod.

Where is Beren described as especially strong? It might be implied by the Leap of Beren--anything else?
