At its most basic form, pumping is the deliberate act of getting light on the fronts of bumps and heavy on the backs of bumps. This reduces impacts and generates speed.
At the highest level — which is where we’re going — pumping is a fully integrated, wavelike movement that allows you to generate massive speed, traction and power. After you’ve dialed in the fundamental pumping movement, you’ll use the same skill for hopping, manualing, jumping and even sprinting. This is the A1 key to Riding at the highest levels.
