The lateral lunge is a spring strengthening exercise because the body doesn’t leave the ground.
In the impact version, the single leg hop, the body leaves the ground as a hop or jump. That is the difference between spring strengthening and spring supercharging, the impact into the human spring mechanism.

Single Leg Hop
Stand with your feet about a shoulder-width apart.
Bend your knees before dropping into a squat while leaning in the direction you want to jump.
Explode out of the squat upward and to the side, swinging your arms upward as you do.
As you land make sure it’s on your midfoot and forefoot.
Don’t let the heel touch the ground until you come to a stop.
These exercises can graduate from lateral shuffle step to lateral shuffle run to lateral shuffle hop.
Each level offers more opportunity for improvement in balance, coordination and agility.
The exercise will help stabilize the foot and its arch complex.
