Yup, as with all things biking it’s simple in practice, much harder in application.
So in brief, compress into the face of the jump (drop heels, let arms follow), decompress as the front wheel approaches the lip, so that you are effectively stood vertical in relation to the ground, let the bike come up underneath you by bending your legs and then use your arms to push the bike forward and down into the landing. Always taper your speed on tabletops. The bike is supposed to land on the downslope, not beyond it. Unless you’re Brandon Semenuk or somesuch, you really don’t want to be jumping right over the thing.
