Personal Trainer (Level 3) works more closely with individual clients and usually:

Do I need to be a member of CIMSPA or REPs?

CIMSPA membership isn't mandatory to work as a PT, but it's highly beneficial for CPD, professional standards, job listings, and credibility. REPs (legacy register) has largely transitioned to CIMSPA. Many gyms prefer or require CIMSPA affiliation.

What happens after I complete the course?

You'll receive your certificate, be eligible for insurance/CIMSPA, and can start working immediately. StudyActive offers ongoing support: CPD resources, alumni network, job guidance, and access to further courses.
