Upon importing all my images into LR I apply an import preset that I created. Honestly for a lot of my images it is all the editing that they need. Having this preset has saved me so much editing time, I strongly suggest that if you use lightroom that you create one for yourself.
Here is the before.
And the after:
It's important to develop one that works with how you usually shoot but the basic settings for mine are +25 brightness, +40 clarity, +14 highlights, -9 shadows, medium contrast point curve. Not a lot, but just enough to add a little contrast and sharpness.
