Need to say what people can expect in a session, what they can get out of working with a trainer.
Address price, time (are all trainers 1hr?), single, duet/triplets.
Address what everyone will get walking through the door but also that each trainer is different. Make it easy for them to understand what they can expect here.
The average person seeking weight loss should see a trainer
Injury rehab is an excellent reason to see a trainer
Sport specific training is another great reason to see a trainer
Anyone can see a trainer!
