how much gym work and how much riding?

But, I want to correct one thing, a pound of muscle weighs the same as a pound of fat, and in fact it is more compact.

1 pound (of muscle) = 1 pound (of fat).

I didn't say 1 lb of muscle weighed more than 1 lb of fat. a pound is a pound is a pound. what I did say is that muscle tissue is heavier than fat tissue. in other words, 1 cubic inch of muscle weighs more than 1 cubic inch of fat.
