HIIT antrenmanları nedir ve etkileri nasıl çalışır?

I’ve been mixing HIIT into my weekly routine for the past year to keep my energy levels up while still finding time for my side projects, and here’s what works for me. The core idea is simple: 20–30 seconds of all‑out effort (sprints, burpees, kettlebell swings, etc.) followed by 40–60 seconds of low‑intensity recovery (walking, light jogging, or just standing). I usually start with a 4‑minute “starter block” (4 × 30 s work + 30 s rest) and gradually add another block each week until I hit 12–15 minutes total. This duration hits the sweet spot where you’re pushing lactate thresholds enough to trigger excess post‑exercise oxygen consumption (EPOC), which burns calories for hours after the session, and it also stimulates mitochondrial biogenesis for better cardio capacity. A couple of practical tips: 1) Use a heart‑rate monitor and aim for 85‑95 % of your max HR during the work phases; this ensures you’re truly in the high‑intensity zone. 2) Keep the rest intervals just long enough to maintain form—if you’re gasping for air, extend the recovery by 10 seconds, but avoid dropping below 50 % HRmax, otherwise the metabolic stress drops. 3) Schedule HIIT no more than three times a week and pair it with at least one full rest day or a light mobility session to protect joints and prevent burnout. Over time I’ve noticed faster VO₂ max gains, steadier blood‑sugar levels, and a noticeable reduction in stubborn belly fat, but the key is consistency and listening to your body—if you feel lingering soreness or a dip in performance, dial back the intensity or add an extra recovery day.
