Here are the main points I was taught when I learned how to ski bumps and to be able to instruct/coach otheres:
1) Look about 3 moguls ahead of where you are, don't fixate on the mogul you're navigating at the moment.
2) Try to keep your shoulders square down the hill and feet together moving as one.
3) The motion you are going for can be imagined like one of your legs pedaling a bike backwards, as your leg extends into the valley of the mogul it should move forward as well, then when it contacts the side of the next mogul you compress to absorb the mogul, and foot moves backward again.
4) Light pole plant on top of every mogul. This will help your timing, BUT you do not want to brutally stab each mogul, or you can put yourself off balance.
Other than that practice will make you better, just keep shredding the moguls and you will get better over time.
