Flow(light) Left jab → Left jab → Left jab → Right cross

Double jab, one-two is a combination where you measure range with the first left jab, land the second, and flow straight into a one-two. The first jab doesn't need to land. You land the second at the range the first one measured, then move on to your power punches, so it works when you want to go first and take control.

Double jab into a one-two (measure with the first): key points

  • The first jab is for measuring and doesn't need to land. You land the second.
  • Use the range where the second jab landed as your guide and throw the one-two straight away. If it doesn't reach, add a step in.
  • If the opponent punches back after the one-two, slip it and fire back right away. Don't stop at avoiding it.

Double jab into a one-two (measure with the first): common mistakes

  • Trying to land hard from the first jab. Your body drifts forward and the punches after the second don't follow.
  • Stopping after the second jab. The opponent resets and the one-two doesn't reach.
  • Planting your feet once you've thrown all four punches. You take the opponent's counter.

Double jab into a one-two (measure with the first): how to practice

  • In shadowboxing, vary the power: the first jab light and short, the second extended to land. Repeat.
  • On the heavy bag, check the distance with the first jab, land from the second and carry it through the one-two. Move your feet at the end before you start the next one.
