How to snowboard through moguls
Use the lower part of your body to absorb the bumps.
Your knees should NOT be locked up and you need to bend with the lower half of your body to absorb the bumps when riding through moguls.
Upper body should be upright and dont bend at the waist.
You want to use the muscles in both legs independently as you will need to use your front leg to pull the snowboard nose up and over the bump before you initiate a turn.
Keep a tight core as you go through the bumps and control your speed to ensure you dont get bucked off a mogul.
