Intentional recovery session after three consecutive strength days (Mar 30, Apr 1 intensity week). Everything felt comfortable throughout — no strain, no neurological load, just controlled breathing and sustained holds. This is the lightest session in the recent training pattern by every metric: lowest avg HR (69 vs. 96-135), lowest calorie burn (50 vs. 194-419), shortest duration. That’s exactly the point. After W3D2 triggered post-session headache and eye ache, the nervous system needed a downshift — not another hit. Smart periodization. Yoga introduces mobility work that the strength-only programming doesn’t address, and the parasympathetic stimulus supports the 48-hour recovery window from yesterday’s intensity session.
