The content was interesting. only comment is the video audios where a bit hard to listen to not because was unclear but some the sound was very far off and others seemed very load. Would be nice for individuals that are more visual learners to have the course material in a downloadable or online accessible document format instead of only the slides and videos

By Susen Maharjan on 6/11/2025

completing this fitness course has been a valuable and rewarding experience. The course provided a solid foundation in exercise science, program design, client communication, and nutrition principles. I now feel more confident in my ability to guide others toward their fitness goals with safe, effective, and personalized programs. The content was practical, easy to understand, and well-structured for real-world application. I'm excited to continue building on this knowledge and helping others live healthier, stronger lives.

By Afia Saeed on 4/25/2025

I really enjoyed the marketing section, because the person explaining it gave examples and made it easy. The guy in the first two sections basically read through the stuff, not explaining difficult terms used, and hardly gave any examples. The lady for the nutrition section did a good job but also didn’t engage much and the quality of her videos wasn’t great. Overall I enjoyed the course and learnt a lot!

By Joy Schroeder on 4/9/2025

The bioenergetics, adaptations, and anaerobic presentations were very informative, but perhaps too academic and in-depth, especially in comparison to the other sections. Thankfully, I have a medical background, and although it's been a long time since I took biochemistry and organ system physiology, it helped me grasp the terminology and principles. Other than that, I believe the course provided the necessary instruction I was looking for as an entry level personal trainer.

By Udemy User on 3/23/2025

Section 1 : It was interesting to know about what happens at a cellular level in the body and the different types of muscles. Though I assume that it would be most important to those who are professional athletes, and of moderate interest to those exercising to be relatively fit. Section 2 : Very interesting section. Learnt some fundamental concepts of exercise program design.

By Sahil Shenai on 11/29/2024

This course covers all necessary topics in good amount of depth. And not just 'what to do' but also 'why to do'. This is important because many times you will be presented with unprecedented situations in life, and knowing basic physiology is going to help you navigate and make good decisions. I am happy that now I am getting a certificate which is approved by ISSA.

By Antonio Clement on 9/27/2024

Excellent course and approved by the greatest ISSA! I recommend this course and you will get your certificate in good time. Certificate Tips: After you complete your course do the following - 1.

I recently completed this fitness certification course, and I couldn’t be happier with the experience! I was looking for such course for a very long time, and I am very happy I stumbled upon this one. As someone who runs a website focused on improving a chest deformity with the help of exercises, I was looking to deepen my knowledge of exercise science and fitness, and this course delivered everything I needed and more. The instructors are incredibly knowledgeable and provided a perfect balance between theory and practical knowledge. The module on marketing and communication was a real eye-opener for me, especially for someone like me who’s in the online fitness space. Austin Moy did a fantastic job teaching exercise fundamentals and workout program design, which were super useful for me. Even though I've been a fitness fanatic for 10 years, I really learned a lot with this course, and a lot of things made sense to me. I also appreciated the take on nutrition for fitness, something that’s crucial for both personal development and working with clients. The course format is flexible, allowing you to work at your own pace, which was perfect for me. It’s also internationally recognized by ISSA, giving it that extra credibility that I was looking for. By the end, I felt confident in my ability to design effective workout programs and ready to start working as a certified fitness professional. If you’re serious about fitness and want a course that covers everything from anatomy to marketing, I highly recommend this one! PS: The course creators were extremely helpful and answered my messages on social media and emails very quickly, and in detail explained everything that I had questions about. Also, there is the option for them to print out the diploma and send it to your address, which is very professional.

By Lucas Leslie on 8/6/2023

Found this to be a good stepping stone class if this is something you are considering it's worth the time to give a good listen but if you are already experienced this may be a little basic for what you are really for and found more of the marketing info more helpful than the fitness sections

By Catherine Gervacio on 6/25/2023

There's unclear audio in the first segment and the slides were just literally read but Trainer Jelena Skender has a friendly and encouraging vibe so it makes me want to continue. I like the content of Coach Austin Moy and Coach Michael Piercy! Lots of learning and they know what they are talking about comprehensively. The lectures of Nutritionist Sandra Krstev Barać were also good, but the audio isn't clear and the slides were a bit blurred.
