Get the iOS AppThis is a Tabata session: 20 seconds of work, 10 seconds of rest, eight times through for a four-minute block. The protocol comes from a 1996 study by Dr. Izumi Tabata and colleagues on Japanese Olympic speed skaters, and the intervals are meant to be genuinely maximal rather than merely brisk.
Count your reps in the first round and treat that number as the target for all eight. The conventional score is your lowest round, which is a deliberate check on going out too hard. If round eight is less than half of round one, you started too fast.
This session is built for people newer to interval training: the movements are low-skill and the volume is manageable, so your form should still hold up in the final round. That does not make it easy — intensity is relative — but it does make it safe to run unsupervised. Finish feeling like you had one more round in you.
Scaling is how this workout stays useful across a range of abilities. Pick the version of each movement that lets you keep moving at a steady pace, and note what you changed so the next attempt is a fair comparison.
Jumping Jacks — easier: step side to side instead of jumping. Harder: switch to plank jacks.
No equipment at all. Everything here is bodyweight, and floor space roughly the size of a yoga mat is enough. This one works in a hotel room, a garage or a corner of the living room.
Warm up before you start the clock. Five to ten minutes of easy movement plus a few light reps of each movement in the workout is enough, and it matters more on short, intense sessions than on long ones.
