As a beginner, I found Kendo to be easier than other martial arts I did (I did mostly wrestling in high school and Muay Thai for a short period, did a month of BJJ before they hiked up the prices for lessons). However, what was stressed during my time with those martial arts was conditioning. Conditioning, conditioning and more conditioning (except BJJ). So, of course, Kendo compared to those other martial arts, comes relatively easier for someone who regularly does cardiovascular and strength training compared to your average couch potato.

That being said, Kendo is a martial art that stresses technique above all. Even if you can eat weights at the gym and run a mile in under 5 minutes, technique will determine your success in Kendo. This is why a girl can beat a guy in Kendo without being physically stronger than him.

I found that you will need to open your mind when you do Kendo. You will have Senpai and Sensei give you advice and sometimes criticize you to improve your Kendo. Your Kendo will NEVER EVER EVER EVER be perfect, you always have to improve.

Other than that, Kendo is the only martial art I have gotten the most abnormal growths and injuries from (blisters and calluses :P). Oh, a lot of etiquette as well!
