Get A Leg Up
Meaning
To get a boost or advantage.
Example
I could get up at 5:00 am to get a leg up on my competition, but I don’t think so.
Origin
This phrase may incorrectly invoke images of a dog raising its leg.
In fact, getting a leg up is from the act of an equestrian receiving help in mounting a horse.
The helper would create a foothold by cupping the hands to heft the rider upward, throwing a leg up and over the steed.
