Why it matters
Different types of movement have fundamentally different effects on the nervous system. Yoga and low-intensity movement tend to activate the parasympathetic nervous system — rest and digest. HIIT activates the sympathetic system — fight or flight. For people who are already running in a chronically stressed state, high-intensity exercise on top of existing stress can push the nervous system further into exhaustion rather than building resilience. If HIIT consistently leaves you feeling depleted rather than energised, your current stress and recovery load is almost certainly the reason.
When Normal helps
Normal tracks your response to different types of movement over time. It finds whether your post-exercise feeling is consistent for each type of exercise and whether your current stress and recovery state is determining how you respond. It finds your personal movement formula.
How Normal finds it
Tell Normal what type of exercise you did and how you felt afterward. Over a month it finds which types of movement consistently make you feel better and which ones deplete you — and whether the pattern changes based on your stress and recovery state.
