Final answer:
An experienced personal trainer, with one year of experience, is likely to get 75% of new clients from referrals and word of mouth, as it is based on the trust built with existing clients and carries a high level of credibility.
Step-by-step explanation:
An experienced personal trainer (PT), with one year of experience, should ideally be able to get 75% of new clients from referrals and word of mouth. This method is often the most effective because it is based on the trust and satisfaction of existing clients, which can be a powerful endorsement to potential clients. Furthermore, a referral usually comes with a pre-established level of credibility, as it is a recommendation from a satisfied customer.
Social media advertising can help to increase visibility but might not be as effective for a one-year experienced PT compared to the strong, trusted network created through referrals. Cold calling and distributing flyers and brochures can also be used as methods of acquiring new clients, however, they may not yield as high of a return as personalized referrals would.
