20 seconds all-out, 10 seconds easy, 8 rounds per set — the real Tabata protocol.

Sustained rounds at the effort that builds the most for the fatigue cost.

Right at the edge — steady pressure, no spikes, no fading.

Real sustained power — the hardest zone that still holds for minutes, not seconds.

Surge above threshold, settle just below, repeat — no full recovery, just like real racing.

"Speed play" — irregular surges by feel, never the same length twice.

Resistance climbs step by step to a peak, then walks back down the same steps.

Short max efforts, full recovery between each — the recovery is as deliberate as the effort.

Resistance climbs one step at a time until it’s genuinely hard — a personal benchmark, not a measurement.
