25. Keep, Skip, or Caution: Sorting Exercise Fact From Fiction with Dr. Lauren Colenso-Semple

Dr. Sheila Wijayasinghe and Dr. Shazma Mithani

The exercise and wellness space is louder than ever and often full of confident, conflicting advice. In this episode, we sit down with exercise physiologist and researcher Dr. Lauren Colenso-Semple to cut through the noise using a simple framework: Keep, Skip, or Caution.

Together, we tackle some of the most common questions and trends people are confused about right now, especially in midlife. We break down what’s evidence-based, what’s overhyped, and where nuance matters.

In this episode, we discuss:

  • Weighted vests and who they may (or may not) be helpful for
  • How much cardio people actually need each week
  • Strength training myths, including whether heavier is always better
  • How often you really need to lift weights
  • Cardio vs strength training and how to prioritize
  • Protein needs for muscle health in midlife
  • Creatine, who may benefit, and who should be cautious
  • Midsection weight gain in midlife and common misconceptions
  • Cold plunges, recovery, and timing around workouts
  • VO₂ max and longevity
  • DEXA scans and body composition data
  • Vibration plates
  • Cycle timing and exercise

We close with one of the most important conversations of the episode: how to decide who to trust online when it comes to fitness and health information.

If you’re feeling overwhelmed by exercise advice or unsure what actually matters, this episode is for you.
