'Nobody cares.....'????
Seriously? Did you know how Daniel Komen nail his speed workouts back in the day? He probably wasn't even breathing at all running fast interval repeats precisely because he came from an existence far removed from not only wireless technology but also all other electrical and electromagnetic gimmicks! Shows how much you don't know about what provides the core foundation for ingenious high-performance training and racing ability.
You only care about superficial training theories that gives you a feeling of false sense of security and attachment and therefore think it could be the outright cause of success. Well, I'm now showing you the cause of the cause, or cause of the cause of the cause!!! If you had thought you found cause about anything on this planet, you can be sure I will always find one that causes that cause of yours!
