How to Find a Good Trainer?

Anneliese Cadena, A-GNP-C, MSN, RN

When it comes to fitness, finding a great trainer can make all the difference between spinning your wheels and making real progress. A good trainer isn’t just someone who knows how to count reps—they should be knowledgeable, adaptable, and committed to your individual needs. But with so many options, how do you separate the professionals from the glorified cheerleaders?


At Vitality, we believe fitness is a part of a broader strategy for long-term health, longevity, and injury prevention. The right trainer should align with those same principles. Here’s what to look for when choosing someone to guide your fitness journey.



1. Look for More Than Just a Certification

Many people assume that a certification automatically makes someone a great trainer. While it’s a good baseline, it’s not the whole story. Certifications like NASM, ACSM, and NSCA indicate knowledge, but experience, continued education, and results matter more.


What to ask:

  • How long have you been training clients?

  • What additional courses or certifications have you pursued beyond the basics?

  • Have you worked with clients who have similar goals to mine?


A great trainer continuously seeks to expand their knowledge, especially in areas like injury prevention, biomechanics, and nutrition.


2. They Assess Before They Train

A red flag? A trainer who jumps straight into a workout without assessing your movement, strengths, and limitations. An initial assessment should include:

  • Posture and mobility testing

  • Strength and endurance baseline

  • Discussion of past injuries or limitations


If your trainer doesn’t take the time to understand your body first, they’re guessing—and guessing leads to injury.


What to ask:

  • How do you assess new clients?

  • Do you track progress with objective data (measurements, performance, or mobility tests)?


3. They Train According to Your Goals (Not Theirs)

Ever had a trainer push you into workouts that feel completely misaligned with your goals? Maybe you signed up for strength training, but they keep making you do endless HIIT circuits. A great trainer listens first and builds a plan around your specific needs.


What to ask:

  • How do you structure programs for different client goals?

  • Can you walk me through your process for designing a workout plan for me?


4. They Focus on Quality Movement, Not Just Sweating

Good trainers prioritize movement quality over making you exhausted. If a workout leaves you feeling beat up with no clear sense of progress, that’s a problem. Your trainer should emphasize:

  • Proper technique over lifting heavier

  • Form corrections and injury prevention

  • Recovery and mobility work


What to ask:

  • How do you ensure clients are using proper form?

  • How do you adjust workouts for fatigue, stress, or injuries?


5. They Educate, Not Just Instruct

The best trainers empower you with knowledge so you’re not dependent on them forever. They should explain:

  • Why certain exercises are in your program

  • How different training styles affect your body

  • Basic principles of nutrition and recovery


A great trainer doesn’t just coach workouts—they coach you on how to take ownership of your fitness.


What to ask:

  • Will you teach me the reasoning behind my training program?

  • How do you help clients build long-term habits?


6. They Align With Your Lifestyle and Personality

Beyond expertise, you need a trainer whose communication style and personality work for you. Some people thrive with tough love, while others need a patient, encouraging coach. Your trainer should also fit into your lifestyle—if you’re a busy professional, you need someone who can help you maximize limited time.


What to ask:

  • What’s your coaching style?

  • How do you adapt training for clients with busy schedules or high stress?


7. They Track and Adjust Based on Data

Progress isn’t just about feeling tired at the end of a session. A good trainer tracks your progress with measurable data, whether that’s:

  • Strength increases

  • Improved mobility or flexibility

  • Body composition changes

  • Performance metrics (VO2 max, endurance, etc.)


If a trainer isn’t tracking progress, they’re guessing. And in fitness—as in medicine—guessing is bad science.


What to ask:

  • How do you measure progress beyond the scale?

  • Can you show me examples of how you adjust programs over time?


8. They Stay in Their Lane

Trainers are not dietitians, physical therapists, or medical professionals (unless they have dual qualifications). Beware of trainers who overstep by offering medical advice, extreme diets, or treatments beyond their scope. A great trainer knows when to refer you to the right professional—whether that’s a doctor, nutritionist, or therapist.


What to ask:

  • How do you handle nutrition guidance?

  • What do you do if a client has pain or an injury?


The Right Trainer Should Feel Like a Teammate

A great trainer guides you, educates you, and helps you build confidence in your body. They focus on sustainable progress, not quick fixes. If a trainer doesn’t ask questions, track progress, or tailor workouts to you, they’re not worth your time (or money).


How to Spot a Good Trainer?

  1. Prioritizes assessments before training

  2. Designs programs based on your goals, not theirs

  3. Teaches proper movement and prevents injury

  4. Educates you so you can eventually train on your own

  5. Adjusts workouts based on progress and lifestyle

  6. Tracks results with real data

  7. Stays within their professional scope


If your trainer checks these boxes, you’re in good hands. If not, it might be time to find someone who does.
