Is there a market niche and certification for ADHD specialty fitness trainer

I am a 52 year old male with ADHD. I want to become a personal trainer and help others who struggle with ADHD. What are some thoughts on this niche as a specialty? A few years ago I was fired from another job due to my ADHD. I fell hard into depression and was having bouts with anxiety attacks. I got back into exercising and decided to train for a half marathon and got into core strength training as well. Since then my life has dramatically been effected. Exercise was my prescription that helped me. I've done extensive research on the impact exercise has with ADHD. Now I'm motivated to exercise regularly not only for my body but also for my brain. My focus, attention, memory, mood and learning has improved with regular exercise.
Would this be considered a viable niche. If so, I would appreciate suggestions for resources, certification and marketing.
