Domaining is a religion.
One of the deadly sins is having a long name.
But to people who don't believe in this religion (regular business people), long is OK sometimes.
The questions in play:
1. Is it the most concise way to describe the thing, without losing the meaning?
Maybe Holistic Fitness is just as good or better, I don't know the industry.
2. What do people search for the most?
Holistic Fitness gets ~1,200 exact searches per month. Your phrase gets ~25 exacts.
The silver lining there is that for those 25 people, your domain could rank higher than the shorter ones, in search results.
So, if someone wants to do this kind of work in their town, they might give you $xx to $xxx for the name.
You might also be holding and renewing it for a few years.
