Readiness
Push. Readiness 82, RHR 40 bpm (excellent, low end of your athlete-normal), HRV 127 ms (mid-baseline, not depressed). Sleep score dipped to 75 (bottom of your typical range) but one night isn't a pattern yet. Day 4 menstrual — Sims frames early-cycle as a strong training window; nothing here says otherwise. Train today's session as planned.
Watch For
Sleep score 75 last night — watch for a second low night before worrying. Back Squat plateau is real (3+ sessions) — Block B rotation to Front Squat handles it soon; don't force extra load meanwhile.
Nutrition
Menstrual day 4 — iron-forward today (Sims), protein floor still 130g on a lift day; hydrate ahead of the Houston heat.
