Highlights
This section introduces the concept that lack of progress in vertical jump is not a motivation problem but a "deficit problem." Athletes often overtrain what they're good at and undertrain their weakest link. The video promises to explain four vertical jump deficits, provide real examples from elite jumpers, and outline simple tests to identify personal deficits.
A deficit is defined as being bad at one specific quality needed for a high jump, relative to one's own potential. The first deficit discussed is the max strength deficit, which is about the maximum force an athlete can produce. The deep back squat is suggested as the easiest way to test this. To improve, prioritize structured max strength work integrated into a training plan, using progressive overload and periodization. The speaker shares his own past mistake of only focusing on basic strength work without proper periodization.
The second deficit is jump technique, which allows athletes to utilize a higher percentage of their produced power during approach vertical jumps. The difference between standing vertical and approach vertical jump height indicates technique efficiency. Elite athletes like Jonathan Clark and Darius Clark are used as examples of individuals with technique deficits, despite their overall athleticism. Jonathan Clark had a 6-inch difference between his standing and approach vertical, suggesting his powerful lower body wasn't fully translated due to technique.
The third deficit is elasticity, which refers to how well tendons store and release energy. Metrics like ground contact times, RSI (Reactive Strength Index), and sprint speed are indicators. If a strong athlete has long ground contact times, slow sprint speeds, and tends to jump from deep knee-bending positions, they likely have an elastic deficit. Chi is mentioned as an elite athlete with a noticeable elastic deficit, excelling in muscle-driven jumps but showing tendencies for long ground contact times.
The fourth deficit is power, defined as the ability to produce force concentrically in a short period. An athlete can be strong and elastic but still lack power. The speaker identifies this as his personal common deficit, stating his jumps improve significantly after power-focused training cycles. Barbell squat jumps, hex bar jumps, and power cleans are suggested tests. Velocity-based training (VBT) devices can provide precise metrics like peak force (peak foss).
The video concludes by revealing a fifth, often overlooked, deficit: health. Injuries prevent consistent hard training and high jumping. The speaker uses his coach, John, as an example, whose progress was limited by health issues despite good numbers in other areas. It's emphasized that addressing injuries is crucial and will lead to more improvement than attempting to train around them. The video ends by encouraging viewers to seek a free diagnosis call to identify their specific deficits.
