The credentials, questions, and green flags to look for when hiring a personal trainer.

Short answer
To choose a personal trainer, look for a nationally recognized certification (NASM, ACE, ACSM, or NSCA) or a relevant degree, experience with your specific goal, a real assessment process, and clear communication. Ask about their approach and pricing, and use a free consult to see if you click before you commit.
1. Check credentials
Start with qualifications. A nationally recognized certification — NASM, ACE, ACSM, or NSCA — or a degree in exercise science signals real, tested knowledge. If you have a specific need like weight loss, post-rehab strength, or functional movement, look for relevant specialty experience too. (For context, Josh Ward holds a BS in Exercise Science and is a Functional Movement Specialist.)
2. Match the trainer to your goal
A great powerlifting coach isn't automatically the right fit for sustainable weight loss or injury recovery. Ask whether they've worked with people like you, toward goals like yours, and what those clients' journeys looked like.
3. Look for a real assessment process
The best trainers don't hand you a generic plan on day one. They assess how you move, ask about your history and injuries, and build from there. If a trainer skips this step, that's a red flag.
4. Questions worth asking
- What are your certifications and how long have you been training clients?
- Have you worked with clients who share my goal?
- How do you assess someone new, and how do you build a program?
- How do you track progress and adjust?
- What are your packages and pricing? Do you offer a free consult?
5. Green flags vs. red flags
Green flags: they explain the why, listen to your feedback, scale exercises to your level, and communicate between sessions. Red flags: one-size-fits-all plans, pushing through sharp pain, no assessment, or vague answers about qualifications.
6. Use the free consult
Chemistry matters — you'll spend real time with this person. A free consult tells you whether you communicate well and trust their approach before any money changes hands.
