Coordination and knee lift. March through the low hurdles with a high knee and a steady rhythm, one step between each.
March or jog through low hurdles with a high knee over each, one step between them. Emphasise a tall posture, a strong knee lift, and a steady rhythm. No jumping load. Build the coordination first, then progress to bounds.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
