Slow strength.
Clearer evidence.
The science, history and open questions behind slow resistance training. From Arthur Jones and the Colorado Experiment to SuperSlow, Mike Mentzer and modern research.
Resistance training has a substantial research base. The claim that exceptionally slow repetitions are uniquely superior does not have the same support. These guides separate controlled evidence, historical reports and coaching philosophies so you can understand both the appeal and the limits.
