  1. Resistance = meeting resistance exercise guideline only; Aerobic = meeting aerobic exercise guideline only; Neither = meeting neither exercise guideline; Combined = meeting both exercise guidelines; TPB = theory of planned behavior, OR represents the change in the odds of a meeting a guideline for a one-unit change in the variables
  2. a High scores indicate higher difficulty in exercise and worse sleep quality
