Whats the point of all these trendy cross-training activities for road cyclists, are they really worth the time and effort, or is it just a fad thats going to fade away in a few years. Every other week it seems like theres a new article or video telling us that we need to be doing strength training, or swimming, or yoga, or whatever else, in order to improve our cycling performance. But whats the actual science behind it. Is it really going to make a difference in our times, or is it just a way for companies to sell us more gear and training programs. And what about the people who just focus on cycling, are they somehow missing out on some magical benefit that the rest of us are getting from our cross-training. It seems like every time someone tries to bring up a different viewpoint, they get shut down by the experts who claim that their way is the only way. So lets hear it, whats the real deal with cross-training, is it a necessity, or just a nice-to-have. And dont give me any of that its all about balance and variety nonsense, I want to know what actually works, and whats just a waste of time.
