INSIGHT

Match Exercise To Muscle Mechanics

  • Neuromechanical matching dictates which muscles a movement will naturally recruit across the range of motion.
  • Choose exercises or machines whose loading curve matches the target muscle's strength curve for better activation.
ADVICE

Pick Machines That Keep Pec Tension

  • Use converging presses or cams that keep pec tension through the full pec range and avoid end-range triceps takeover.
  • Prefer machines with a matching loading curve so the pecs remain the prime mover at all reps.
ANECDOTE

Teaching A Worker To Curl Properly

  • Dr. Stevenson trained a construction-worker client who reflexively used his whole body instead of isolating biceps curls.
  • He had to physically restrain movement and teach concentrated curls to create a new motor pattern.
