In 1973, the Colorado Experiment reported muscle gains so extreme they’re still debated today.
Only two subjects. Minimal workouts. Maximum intensity.
Was it perfect science? No. Was it average trainees? No.
But it raises a question most lifters avoid:
Is more really better…
or is better just harder?
Muscle doesn’t respond to comfort. It responds to intensity — followed by recovery.
Food for thought.
