I’ve narrowed it down to these four:
The makers of fit bodies and spirits
Stay fit forever, stay young forever
Champion training for everyday people
Get in the best shape of your life.
These aLl say very different thing to me, and like Lexde said I’d think carefully about who you are targeting
and why.“Fit bodies
and spirits” sounds like you are going to spend equal time on their inner selves. I picture a lot of meditation or empowerment thinking or things like that.
“Stay fit/young forever” sounds like you are focusing a bit much on beauty (youth). Also, it’s clearly a lie: we are all going to get old and die. Fit through all stages of life is more accurate (and a slogan of a group near me).
“Champion training” sounds like you a training them for a specific event, like a marathon or bike race. To me training has a much different mindset and image over fitness or exercise. That could be a good or bad thing depending on how you want to find and focus your clients.
“Get in the best shape of your life” sounds more like the target audience you seek, but is a bit of a cliche in the fitness industry. It will appeal to 30-40 something everyday joe/Jane but not to former athletes (who deeply understand they won’t and don’t want to eclipse to their early 20s selves) and I imagine few 50+ will believe they can be better than they were several decades earlier with all their surgeries, deterioration and age-based limits.
