Two springs together more elastic?

Based on the equation: 1/ktot = 1/k1 + 1/k2
Why is it that the reciprocal of the total spring force is equal to the reciprocals of each spring constants??
I know how to derive the equation, but what is the physics behind it??
The total spring constant is much less than those of the two individual springs... smaller k means that the spring is more elastic... why does two combined springs cause the elasticity to increase??
I know I'm asking a lot of questions.. but any help would be appreciated! :)
