This podcast episode features Elliott Hulse discussing the different layers of strength beyond just physical strength. He describes four layers: 1) Neuro-muscular strength which is physical strength in the gym. 2) Physiological strength which is internal health like digestion and hormones. 3) Energetic strength which is psychological strength and character. 4) Presentable strength which is how one serves and inspires others. Elliott emphasizes that all layers must be developed together and that true strength comes from facing challenges instead of avoiding them, as facing resistance is what allows growth.
