In this preview, we cover:

  • Lead in Your Supplements? 🤯 The recent controversy and why you need to check for third-party, batch testing. We discuss the low lead content of Barbell Medicine's whey and why plant-based proteins, like vegetables, naturally carry higher risks.
  • The Problem with Group Class Programming: While F45, CrossFit, and Orange Theory are great for adherence, their circuit training often compromises total training volume, force production, and loads, which reduces exercise-related adaptations.
  • Stop the Endless Stretching! Stretching alone does not reduce injury risk, decrease soreness, or improve performance. Better to use that time for actual strength training.
  • Weight Cutting: Is 20 lbs Too Much? Get the strong recommendation against attempting an aggressive weight cut for a meet, particularly if you are cutting more than 2-5% of your body weight for a 2-hour weigh-in.
  • Isometrics vs. Dynamic Exercise: Isometrics are best as a starting point for those who cannot tolerate any dynamic joint movement due to pain. However, dynamic exercises are generally better for strength and health adaptations.
  • Deadlift Bar Slack: Learn about the two sources of slack in a deadlift system and why practicing with a deadlift bar (which is longer and thinner than a standard power bar) is essential before a competition.
  • Garage Gym Platform: Do I Need One? Why building an 8x8 platform is recommended for lifting, primarily to eliminate the floor slope common in garages and provide a level, solid surface.
