Most Jump Programs Don’t Measure the Most Dangerous Moment
Take-off gets all the attention. Landing causes most of the damage. Poor shock absorption shows up as: – knee flare-ups – Achilles irritation – ankle instability – nervous athletes post-injury If landing mechanics aren’t trained and measured, injury risk compounds quietly. Are you testing and coaching landings — or just assuming they’re fine?

Core Strength Isn’t About Abs — It’s About Force Transfer
Multiple coaches keep saying the same thing in different ways: Force leaks happen in the middle. Weak or poorly trained core = – force never reaches the floor efficiently – increased joint stress on landing – strong legs that don’t express power Core isn’t decoration. It’s the bridge between strength and explosion. How are gyms training core specifically for jump transfer — not aesthetics?

Why Strong Athletes Still Jump Low
Seeing this everywhere lately: Athletes with impressive lifts but – slow ground contact times – deep countermovements – poor force recycling Strength is there. Elasticity is not. Heavy lifting without velocity, rhythm, and landing efficiency just shifts stress to joints and tendons. Strong legs don’t guarantee high jumps. Efficient force transfer does. How are coaches rebalancing strength vs elastic work?

Why Jump Injuries Keep Repeating (Even in “Good” Programs)
One pattern keeps repeating across gyms and clubs: Athletes don’t get injured because they jump.They get injured because foundations are skipped. Knees, Achilles, ankles, hips — they cluster when: – Load increases before mechanics – Volume increases before elasticity – Sport exposure outpaces S&C buffers Injuries aren’t random. They’re the tax paid for rushed progression. Curious how others are sequencing foundations before volume.
