Are you a morning person or a night person (Lark or Owl)? Do you enjoy spending time outdoors, or do you prefer not to deal with weather? Are you motivated by competition? Do you enjoy exercising to strong music and a driving beat, or do you prefer a quiet background? Do you respond well to some form of external accountability (a trainer, a running group), or is internal accountability sufficient? Do you like to challenge yourself with exercise (learning a new skill, pushing yourself physically), or do you prefer familiar activities? Do you like sports and games? Is it inconvenient for you to take a shower afterward?
