Chasing the Pump

This is a bodybuilding phrase which means increasing your muscle pumps during your strength training workout. When you chase the pump, your veins pop out and your muscles become engorged with blood.

Typically, you can increase your muscle pumps when you consume nitric oxide (N.O.) prior to your workout. This compound increases vasodilation, which, in turn, regulates blood pressure levels and facilitates nutrient uptake. Good vasodilators include l-citrulline, beetroot juice, and 70 percent dark chocolate.
