Can just 20 minutes with a personal trainer really make a difference? In this episode, Amy Hudson and Dr. James Fisher explain why effort – not time – is the true driver of fitness results. From the science of stimulus to the dangers of overtraining, they reveal how shorter, smarter workouts can transform your body and redefine your approach to exercising.

  • Amy Hudson and Dr. James Fisher discuss whether the amount of time you spend exercising is indicative of what results you should expect.
  • Amy kicks things off by introducing the 2x 20-minute approach the Exercise Coach’s personal trainers advise their client to embrace.
  • Some clients ask whether they should exercise more to accomplish their fitness goals...
  • Dr. Fisher touches upon the inefficiency or lack of quality that’s almost always tied to working or exercising for long periods of time.
  • According to Dr. Fisher, what we need to think about in terms of exercise is stimulus.
  • Exercise is the stimulus to adaptation, it’s not the adaptation in and of itself. 
  • The goal is for exercising to provide the stimulus to our body to improve our cardiorespiratory fitness, our ability to deal with blood lactate accumulation, to recruit muscle fibers, get stronger, and increase muscle size and our metabolism.
  • Dr. Fisher and Amy talk about the danger of overtraining and what that may lead to.
  • A 20-minute session with a personal trainer can do wonders when it comes to your fitness goals – Dr. Fisher and Amy explore why that’s the case.
  • Remember: the key is not how often and for how long your train but it’s effort level you’re working at.
  • “What we encourage our clients to do is, basically, to become more in tune with their own body to understand the sensation that the stimulus of a full effort of an exercise session gives your body, and to understand how long your recovery will take,” says Amy.
  • Amy has noticed how eye-opening it is to her personal training clients to get to know their own body, see and feel it respond to the stimulus that we’re creating, and watch it change.
  • Dr. Fisher and Amy discuss the importance of following a sustainable workout.
  • Dr. Fisher and Amy point out the difference – and common mistakes – between a workout at a regular gym and a session with an Exercise Coach personal trainer.
