Science-Based Ranking of Unconventional Exercises Reveals One S-Tier Movement
Fitness expert evaluates strange gym exercises using evidence-based criteria, finding most fall short except one standout movement.
Summary
Fitness researcher Jeff Nippard systematically evaluated seven unconventional gym exercises using a tier-ranking system based on safety, effectiveness, and practical application. Most exercises received middling grades, with several earning A-tier status for specific benefits like back pain prevention and superior muscle activation. However, only one exercise achieved S-tier ranking: the Smith Machine JM Press, which combines tricep development with bench press accessory benefits while allowing safer progression to failure. The analysis highlighted how exercise modifications can dramatically improve safety and effectiveness, while momentum-based movements like kipping pull-ups provide minimal muscle-building benefits despite their popularity in certain fitness communities.
Detailed Summary
Exercise selection significantly impacts training outcomes, injury risk, and long-term physical health. Poor movement choices can lead to joint problems and suboptimal muscle development, while evidence-based exercise selection supports healthy aging and functional longevity.
Fitness researcher Jeff Nippard evaluated seven unconventional exercises using scientific criteria including joint safety, muscle activation, and practical application. The Jefferson curl, despite appearing dangerous, earned A-tier status for back pain prevention when performed with proper progression. The reverse Nordic curl received similar recognition for providing superior quadriceps stretching compared to conventional exercises.
Several exercises showed mixed results. The calf machine shrug demonstrated excellent upper trap activation without grip limitations, nearly achieving S-tier status. However, behind-the-neck presses received D-tier ranking due to shoulder joint stress, while kipping pull-ups earned F-tier for reduced muscle activation despite momentum assistance. Keenan flaps, popular on social media, received C-tier for adequate lat isolation but awkward execution.
The standout finding involved the JM press comparison. While the barbell version earned A-tier for tricep development and bench press assistance, the Smith machine variation achieved S-tier status. This modification eliminates stabilization challenges, allowing safer progression to muscle failure while maintaining all strength-building benefits.
These findings emphasize how small exercise modifications can dramatically improve safety and effectiveness. For health optimization, prioritizing joint-friendly movements with clear progression pathways supports sustainable training practices that contribute to long-term physical function and injury prevention throughout the aging process.
Key Findings
- Smith Machine JM Press ranks as the only S-tier exercise, allowing safe progression to failure
- Jefferson curls prevent back pain when started light with gradual weight progression
- Reverse Nordic curls provide superior quadriceps stretching compared to conventional exercises
- Calf machine shrugs offer excellent upper trap activation without grip strength limitations
- Kipping pull-ups reduce muscle activation through momentum, providing minimal training benefit
Methodology
This analysis comes from a tier-ranking video by Jeff Nippard, a respected evidence-based fitness educator with a background in biochemistry. The evaluation uses practical training experience combined with biomechanical principles to assess exercise effectiveness and safety.
Study Limitations
The rankings represent one expert's opinion based on practical experience rather than controlled research studies. Individual biomechanics, injury history, and training goals may influence exercise suitability, requiring personalized assessment before implementation.
