Hi Lynn. In my opinion, the best way to “deal with burnout” is to AVOID it. As trainers, we are primarily in the business of helping others prevent issues or health-related problems. We owe ourselves that same consideration. So, I say do things on the front-end that will help avoid burnout. What are some of these? For me it includes: not over scheduling my time; allowing for frequent breaks; eat/exercise and rest adequately; have “another life” outside of training; embrace and enjoy my outside interests (e.g. friends, family, hobbies, recreation); and ANYTHING ELSE that you may do for taking care of yourself.
I hope that this helps.
