Uhm, no. It's not a matter of opinion. That's why I
SAID what I
SAID. There's a ton of data regarding specific adaptation to imposed demands that says if you want to be fast on the bike, you gottat train fast on the bike.
Some core work is not going to get in the way of bike training, so not a bad idea, although Graeme Street be damned, there's not a lot of data that it will make you faster.
Other cross training, such as weight lifting and running, in season, is going to limit the training load you can hande on the bike and be counterproductive.
So the opinion element is really a priority issue. If your priorities are generalized fitness,health, fun, sure cross train.
If you want to be fast on the bike, train long, hard, and smart on the bike.
