Broad Jump. Horizontal power, the same direction as acceleration.
Lateral Lunge. Strength in a wide side step that loads the adductors, the muscles most groin injuries involve.
For soccer, lateral lunge rates higher on our research criteria: more injury protection. Broad jump carries over more directly to soccer. Both are good choices that build different things for soccer, so a plan can use both.
About the same: both are easy to learn.
