How to set French contrast from post-activation potentiation
Post-activation contrast windows stay useful when coaches write French-contrast heavy/plyo/weighted/assisted stacks from those pairs—not when every hard session ends with vague plyometric-stack notes.

Start from the current post-activation contrast window
A useful French-contrast sequence starts after the post-activation potentiation contrast window is already written. Read those contrast pairs for which residual windows they sit inside and how long the rest intervals last, then decide which heavy, plyometric, weighted, and assisted stations should stack inside each contrast window. This is a reading method for building the French-contrast sequence clients open—not software evaluation of technique-cue logging tools, meet-day tools, block-load tools, mesocycle tools, macrocycle tools, periodization tools, block-periodization tools, undulating tools, DUP tools, linear tools, reverse tools, conjugate tools, wave tools, concurrent tools, polarized tools, flexible tools, reactive tools, dual-factor tools, ATR tools, phase-potentiation tools, post-activation tools that mainly write contrast pairs without French-contrast stacks, autoregulation tools, taper or peaking tools, deload tools, or progressive-overload tools that mainly chart planned-vs-performed load.
Keep the French-contrast stations explicit
If the only plan after the contrast window is somehow into explosive work, insert the heavy station, plyometric station, weighted explosive station, assisted station, rest intervals, and which post-activation contrast window the stack sits inside so productive contrast sessions do not turn into unstructured improvisation across the block. Prefer readable French contrast over vague plyometric-stack notes. Ignore the urge to rewrite accessories and session order when only the French-contrast sequence needs an update.
Write the French-contrast sequence on the program before the next hard session
Even clean French-contrast stations fail if clients still open bare post-activation contrast pairs with no stacked stations. Put the French-contrast sequence beside the post-activation contrast window on the assigned program, and note which contrast pair drove the prescription so next review can judge whether the stack still fits.
Keep the Lyfta nudge natural
When the French-contrast sequence is clear, a product like Lyfta Coach helps if assigned programs and individual workout logs stay in the same place coaches already edit.
