WORKOUT TIMERS

Tabata workout

Four moves, one Tabata block each, 20 seconds on and 10 off, with a timer ready to run

Most Tabata classes stack several blocks of 8 rounds, 20 seconds of work and 10 of rest, with one exercise per block and a minute of rest between them. This one has four blocks, so with a warm-up and cool down it takes about 26 minutes. It isn’t the original Tabata protocol, which was a single all-out block on a bike: read what the original study did.

Total time: 26:20

Warm-up, cool down and blocks

Ready when you are

05:00

Keyboard: Space starts or pauses, ← and → change interval, M turns the sound on or off, F goes full screen.

Keep this tab open and in front: browsers can slow down timers in background tabs. The Cero app keeps going with your screen locked, on your Apple Watch and in the Dynamic Island.

The workout

Blocks 1 to 4, in order

  1. Block 1, squats: or jump squats, if you want it harder.
  2. Block 2, push-ups: on your knees when you need to.
  3. Block 3, mountain climbers: fast, with your hips low.
  4. Block 4, burpees: step back instead of jumping to make them easier.

The timer counts the 8 rounds of each block, then gives you a minute of rest before the next exercise.

Make it easier or harder

  • Easier: two or three blocks instead of four, with up to 2 minutes of rest between them.
  • Harder: a fifth block, such as kettlebell swings or high knees.
  • Your own moves: keep one exercise per block, and alternate legs, upper body and core.

Run it in Cero

  1. Create an advanced timer and add the Tabata (20/10) template, once for each block.
  2. Name each block’s work intervals after its exercise.
  3. Add an interval of a minute of rest between blocks.
  4. Save it, and run it on your iPhone or your Apple Watch.
