From The Coaches Inside
Andrew Ussher offers a scientifically robust approach and fresh perspective on energy system development, introducing a practical method to developing conditioning that I believe truly fills a gap between what is typically taught in education systems and the essential demands of real-world, high-level application. The calculated system Andrew presents for assessing, measuring, and progressing training is a definitive game changer, and these methods have directly influenced how we program and train our UFC athletes.
This mentorship was an incredibly valuable experience that elevated the way I program for athletes. Rather than relying on generic templates, I now feel confident adjusting work-to-rest ratios based on each athlete’s unique physiological profile. One of the most impactful parts was the opportunity to upload real athlete data and watch Andrew walk through his analysis in real time.
Michael DaCostaMuay Thai S&C CoachOne of the most valuable aspects of the course would be the authenticity. Many programs tout their own ready-made approach to handling performance. With this program it brought back the idea that nothing is written in stone and you need to adapt to the athlete, the environment and the timing.
The development of energy systems presents a multifaceted and complex challenge for high performance sport staff. Andrew delivers exceptional clarity on a complex topic, skilfully combining cutting-edge research, sound theory, and real-world case studies. If you’re seeking practical insights you can immediately apply in the field, this mentorship comes highly recommended.
Mitch PembertonNRL Strength & Conditioning CoachReally enjoyed the testing side of things and how data can be leveraged to provide more accurate conditioning prescriptions. Something I’ve done in the past but not with this level of detail. Has solidified a lot of my thoughts on conditioning as well as providing me with some valuable take aways to integrate into my current conditioning protocols.
Caleb HandleyBoxing S&C CoachAndrew distilled a lot of different areas of physiology that get thrown around in this space but are never clearly defined, and put them into very easy, simplified concepts. He gave theory, practical information, then actual practice with real data analysis from his top athletes — which I didn’t get at university.
Peter ClarkS&C Coach — Master of Clinical Exercise Physiology studentThe ESD mentorship is much more than just simple online courses. Andrew is going out of his way to answer your questions and giving extra content. The mentorship completely changed my approach of conditioning for sport.
Vincent DarchezMMA FighterThe most valuable things for me were the accessibility to Andrew — he was always open to solve your questions no matter what — and the knowledge of the course itself, with a lot of interesting things about physiology and how it works in the “real world”, something that is often missed.
Bruno VerdugoBSc Physical Activity & Sport Sciences — Boxing & S&C CoachI learned so much about conditioning for sports and especially for combat sports. The knowledge was practical and I could implement a lot myself. When I had questions I could always ask them directly to James or Andrew. I would recommend this mentorship for coaches and athletes who want to learn more about conditioning.
Daniel KuduschevAmateur Boxer & Sport Science UndergraduateI found a lot of the research papers shared with us very interesting and good reads. All the research that was shared with us, it was very valuable and very insightful.
Everything was amazing and made simple even for someone like me that has not any kind of University background. The most valuable part was definitely Andrew’s willingness to help anyone in need to better understand the subject, even with 1-1 live chat.
