One long sustained effort — build steadily to peak effort, then a long easy release.

Separate hill efforts with full recovery between — not one long climb.

Undulating terrain — climb straight into descent, straight into the next climb, no flat recovery.

One sustained climb, one steady effort — no stages, no surges, just the grind.

Seated into standing, same climb — alternating position within each set, full recovery between.

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

Two long climbs at one hard, sustained effort — the classic "2x20" climbing session.
