Mutzel draws directly from a slide he has presented internationally, summarizing the literature. He breaks the body's sagittal planes: for chest, presses or push-ups; shoulders, military presses; posterior chain, deadlifts and hip thrusts; quads, squats or leg presses; back, pull-ups and rows. He stresses compound (multi-joint) movements over isolated exercises like bicep curls, which he calls 'finishers.' The recommended rep range of 6-15 is based on a sports medicine paper, but he personally advocates aiming for failure around 8 reps to ensure progressive overload. For busy schedules, supersets—e.g., alternation squats with pull-ups—can maintain stimulus while saving time. He warns against jumping straight into CrossFit without learning power lifts and Olympic lifts first, but acknowledges CrossFit's advantage of pairing resistance with cardio through minimal rest intervals. The overarching goal is to preserve muscle as a protective organ against hypertension, insulin resistance, and premature death.
Resistance training improves mitochondrial function within muscle fibers and reduces fat infiltration (intramuscular lipid). This enhances insulin sensitivity and may lower blood pressure by improving vascular function and reducing systemic inflammation. Muscle mass acts as a metabolic buffer, countering the insulin resistance and hypertension that drive cardiovascular events.
Mutzel mentions that he has presented this exact protocol around the world and aims to improve his own VO2max yearly while maintaining muscle mass. He implies he follows these principles personally. He also notes that many of his metabolically healthy clients who follow similar tenants have low CRP levels.
you need a minimum of four weekly sets per muscle group. ... aim between six and 15 reps. ... you should start to really struggle around rep, you know, around eight to 10 to 12
