"This session takes the traditional intermittent-style VO2max intervals and shortens them to focus more on maximum power and anaerobic capacity. Start with a Z2 warmup followed by 4 max sprints to prepare the body. Then the main sets are 4 x 20 sec on/10 sec off. During the "on" segments, go almost maximal power. Focus less on the power targets and more on the RPE. Keep just enough left in reserve so you can finish the set, but it is expected that your power will decrease from the first rep to the fourth. You should finish each set feeling like you dug very deep."

The breakdown

Inside the workout

Intermittent VO2 intervals shortened until they target maximum power and anaerobic capacity instead. Team AMANI's session is about W′, the reserve above critical power, and about the ability to dig very deep six times in one ride.

Four fifteen-second sprints after the warm-up prepare the body. The main work is six sets of four efforts of twenty seconds on and ten seconds off at 160–250% of CP, with fifteen minutes of zone 2 between sets. The instruction is to ride the on segments almost maximally and by feel, keeping just enough in reserve to finish the set; power is expected to fall from the first rep to the fourth.

Vekta writes the efforts as a range of CP and the W′ preview shows each set draining the battery to near empty, which is the design. The fifteen minutes of zone 2 between sets are long enough for W′ to recover, and the trace afterwards shows whether it did.

A race-block session, once a week, fresh, outdoors or on a trainer that can take repeated near-maximal efforts. Judge it by RPE first, as the team do.

DISCIPLINE

The stimulus

Neuromuscular, explained

Maximal, explosive efforts that train the nervous system and the top of the curve.

What it is

Very short efforts, five to sixty seconds, at 180% of critical power and above, with full recovery between them. Sprints, standing starts, torque efforts and short hill attacks live here. In Vekta's classification anything above 180% of CP is neuromuscular.

Why it matters

Peak power, Pmax, is one of the three numbers in the performance model, and it is the one most riders never train. It decides who wins the sprint, who makes the split when the road kicks, and it feeds the whole power curve: a higher top end makes every effort below it feel easier.

If you ride it

If you ride it

Quality over quantity. These are the only intervals where you should stop the set as soon as power drops, because the point is the maximum, not the fatigue. They are best placed early in the week or before a hard session, never after a long ride.

If you coach it

If you coach it

Track Pmax and the five-second peak over a block; both should move within weeks. Recovery between efforts is the lever: cut it and the session becomes anaerobic capacity work, which is a different adaptation.

The AI Workout Builder handles the nested structure, and the head unit shows the targets. Afterwards the peaks tab flags the best efforts, and the trophy view shows whether the session produced an all-time or eight-week best.
