Why is fitness so hard to gain?

Chris Rosenkranz: Becz it's easy to gain weight rather then of lossing and fitness.

Raven Purl: Its not hard to gain, it just takes a lot of work and persistence. You have done nothing for the last year, so you cant expect to be as fit as you were a year ago. Think about how long you had been training last time to get to the fitness level you were at. It will only take a couple of months, if you keep at it, and you will be feeling your best again. You have to learn to push past your comfort zone to be a boxer. That's what its all about.
