OUTLAST THE 90.

A 30-day progression built for football performance.

Phase 1
Phase 2
Phase 3
Phase 4
PHASE 1

ADAPTATION

Days 1–7

Your legs begin adapting to resistance. Movements feel heavier, but you start building stronger recruitment in every stride, turn, and touch.

PHASE 2

FORCE DEVELOPMENT

Days 8–14

You gain control under resistance. Strides become more powerful, balance improves, and your body starts generating more force in each movement.

PHASE 3

SPEED TRANSFER

Days 15–21

You start feeling the difference without the weights. Movements feel lighter, sharper, and more explosive during training and match situations.

PHASE 4

MATCH PERFORMANCE

Days 22–30

Your speed and power translate into real play. Quicker first steps, stronger duels, and better control under pressure.
