Renaissance Periodization - Every Gym Machine Ranked by Exercise Scientists
The conversation revolves around the evaluation of different gym machines, focusing on their effectiveness for muscle growth. The speakers emphasize that machines which prioritize muscle stretch over contraction are more beneficial for hypertrophy. They critique common machines like chest press, lat pull-downs, and leg extensions, highlighting their shortcomings in resistance profiles and range of motion. For instance, many chest press machines fail to provide adequate stretch, and lat pull-downs often have a backward resistance profile. They suggest that machines with cam systems that adjust resistance to be easier at the contraction and harder at the stretch would be ideal. The speakers also discuss the potential for new equipment designs that could revolutionize gym workouts by better targeting muscle growth through improved resistance curves and ergonomic designs.
Key Points:
- Machines should focus on muscle stretch rather than contraction for better hypertrophy.
- Many current machines have poor resistance profiles, limiting their effectiveness.
- Cam systems can enhance machines by adjusting resistance appropriately.
- New equipment designs could significantly improve workout effectiveness.
- Evaluating machines based on their ability to provide a full range of motion and proper resistance is crucial.
Details:

4. 🦵 Arm Machines: Hits and Misses
- The preacher machine is criticized for causing pain due to poor shoulder mobility and a suboptimal force curve, highlighting the need for better shoulder support and a more efficient design.
- Machines often fail to allow full elbow extension or a satisfying range of motion, limiting their effectiveness mainly to the middle range, suggesting a redesign for full motion capability.
- Seated bicep curl machines frequently lack cam adjustments, leading to poor load distribution; however, rare high-quality machines can achieve a B tier in quality, emphasizing the benefit of cam adjustments.
- Seated tricep extension machines, especially the preacher variants, are deemed ineffective and painful, indicating a need for designs that enable proper force generation and stretch.
- There is a demand for arm machines that offer more freedom in motion and improved stabilization to enhance their effectiveness, pointing to a market opportunity for innovative designs.
- Atlantis machines are praised for features like backpads that provide better support, setting an example for other manufacturers to follow.
