💡 How does progressive overload with sand loaded vests impact joint stress during high intensity intervals?

Add steady external mass changes ground reaction forces across your lower body mechanics. Here is how the setup actually helps:

- Gradual weight increments train stabilizer muscles to absorb impact without overstriding on hard surfaces

- Balanced torso packing limits upper body sway so shoulder girdles maintain proper alignment

- Targeted resistance spikes metabolic rate while extending recovery time between heavy sets
