Of course they're not exactly the same thing, so even if it'll probably give you a bigger match book, it won't carry over 100 %.
They're so different, is why I asked. Common sense would say that at least the cardio and aerobic would carry over, but I'm not so sure of even that. Curious for personal anecdotes.
