Kat explains why consistent training can suddenly feel harder—when the same squat weight feels heavier or easy runs feel slower, especially around week eight—and reassures listeners that fitness often hasn’t vanished but is hidden under fatigue. Drawing on coaching busy women and her own experience peaking for a 230-mile Pennsylvania Appalachian Trail FKT, she outlines six common causes: accumulated fatigue that lifts with a deload, combined life-and-training stress (“full bucket”), under-fueling (“empty tank,” including GLP-1 appetite effects), mismatched adaptation speeds among cardio, muscles, and connective tissue (“speed gap”), over-focusing on a single metric, and lack of a structured plan. She also flags symptoms that warrant medical evaluation (persistent exhaustion, repeated illness, elevated heart rate, irregular periods, worsening localized pain, dizziness) and emphasizes durability, recovery, and learning to read your body as the real payoff of staying the course.
