What I've seen of people who've trained directly (via youtube) under the Gym Jones crew directly seems commendable and well thought out. Conceptually, they train athleticism and quality of movement beneficial to increasing strength, at least from what I can gather via their online presence. That being said, the worst CF coach/gym owner I've ever had had received certifications from Gym Jones that I thought were legit (They were framed and hung on the wall). I was impressed by all her plaques on the wall as a beginner during my own training, but eventually considered said certs to be a joke by continuing my training, education, and communication with the more legit people working out at the gym and losing faith in her programming. I understand this situation might be due to having a singular shitty owner/coach programming for 100+ folks, but I think that if this said individual was able to pass their test, it might be a bit soft in the same vein that folks criticize CF L1 of being. I've not taken either test, so I can't say for certain.
