How fast is
your jab?

The speed test measures your jab and your cross in metres per second, how quickly you react to the call, a timed 1-2-1-2 and a ten-second flurry. It’s free, it takes a couple of minutes, and there’s a board to beat.

How it goes

Four parts, flat out

Set up the way you would for a session: phone propped up, two metres back, head to hips in view. Your coach calls each part and beeps you in.

  1. 1time

    Your height

    Asked once, to the centimetre. It turns what the camera sees into metres.

  2. 5jabs

    Jab on the beep

    Guard up, wait for it, throw. Your speed and how quickly you reacted.

  3. 5crosses

    Cross on the beep

    The same with your rear hand, driven from the hip.

  4. 3×1-2-1-2

    The combination

    Timed from the first punch to the fourth, and how much speed you kept.

  5. 10seconds

    The flurry

    Straight punches, as fast as you can. Every one counted.

How it measures

Metres per second, from one camera

  • Your size sets the scale

    Your torso is a known share of your height, so every frame knows how many metres it shows.

  • Depth from your arm

    A jab comes at the camera. How short your arm looks tells how far it has reached toward it.

  • The whole punch, fitted

    Fast arm movements follow one known curve. Fitting it to every frame finds the peak, even between frames.

  • The middle of five

    Your result is the middle of your five, so one lucky or clumsy punch doesn’t decide it.

Yardsticks

What fast looks like

Competition boxers, measured with lab motion capture. Yours are thrown in the air and read by a phone, so use these as a guide and your own last test as the number to beat.

The 1-2-1-2

From the first punch to the fourth, competition boxers’ average.

The board

Something to beat

  • This week, and all time. A fresh board every Monday, and one that keeps your best.
  • Ranked by your fastest hand. Your 1-2-1-2 time and your flurry count sit beside it.
  • First name and initial. Enough for a friend to find you, never your full name or email.
  • With a free account. Without one, your results stay on your phone.
