Yep, Level 2 USAC coach here. But remember, there have been entry level 3 coaches who have help create World Champions, and Level 1 coaches who only work with beginners. Experience and the application of knowledge really overrides certification levels. Ive worked with brilliant doctors, and doctors who seemed to really struggle with basic periodization principles. Certifications are a place to start when looking for the right person to work with, but a good conversation with them will really tell you if they are right for you. I recently had a conversation with an old school trainer who was touting principles that were generally accepted 3 decades ago, but have long been disproven or shown ineffective. Yet this person seemed to be stuck at a certain place in time as far as his/her understanding of training and adaptations. Good coaches, trainers, physicians and the like really need to try and keep up with the newer and more effective methods and practices. Luckily we are seeing a lot more of this in recent years, and a lot of that is likely due to this here new-fangled interweb.
