45-7-6 StairMaster: Smart or Silly?
The “45-7-6” trend—45 minutes on the StairMaster at level 7, six days a week—is everywhere. In this quickcast, Chris explains what it is, why it’s viral, and how to test it once or twice without wrecking your joints or stalling your strength gains. You’ll learn simple cues to actually hit your glutes (not just quads), why going hands-free matters, and how to use the talk test to keep it aerobic. We also cover why number-based cardio formulas keep cycling through social feeds (novelty sells!) and finish with the Catalyst plan that always works: consistently varied strength + metabolic training you can sustain for years—think full-body lifts 2–3x/week plus a rotation of Zone 2 and short interval work. Trends are fun; results come from posture, programming, and patience.
