It's the… Incremental exercise means ramping up intensity steadily until you hit your limit. It's the standard protocol for measuring VO2 max in a lab, but you can also apply it to everyday training. I use incremental climbs on my treadmill or bike to find my sustainable threshold. This page explains how to run your own incremental test without fancy gear and what the results reveal about your current aerobic fitness. Incremental exercise is the practice of making small, sustainable additions to your movement routine, not overhauling your life overnight. It's the opposite of the all-or-nothing approach that leads to burnout and decision fatigue. On dorsi, you can build this into your daily training with adaptive adjustments that match your current capacity. Even modest changes add up: just 11 minutes of moderate activity per day can reduce all-cause mortality risk by 23%. The key is consistency, not intensity. Posts like "How to Get a Great Workout in 20 Minutes, With Zero Planning" and "5 Signs You Have Workout Decision Fatigue" get at the same idea, removing friction and starting small. This page dives into the science behind incremental increases and how to apply them without overcomplicating your training. ## Set your starting load and step length Pick a warm-up workload you can sustain for 5 minutes easily. For running, start at a conversational pace. Cycle? Try 100 watts. Each stage should last 2-4 minutes - long enough to reach steady state. Shorter stages risk overshooting your true lactate curve. I'd start at 50% of estimated max and go from there. ## How do you choose the increment size? A 10-15% increase in load per stage is a safe bet. Too small and you'll fatigue before hitting max. Too big and you skip over your threshold. For a 20-minute test, 5 stages total is typical. On a bike, I've used 25-watt jumps. On a treadmill, try 0.5 mph or 1% grade every 2 minutes. Adjust based on your fitness level. ## Monitor RPE, HR, and power or pace Don't just stare at your watch. Call out RPE on a 1-10 scale after each stage. Heart rate lags, so use it retrospectively. If you have a power meter, log that too. Your Dorsi app can sync this data. The key is seeing when HR drifts upward despite constant power or pace - that's a threshold marker. ## Stop at volitional exhaustion or form breakdown The test ends when you can't maintain the required effort. That's your V O2max or peak output. But also bail if your running form turns to shit or you feel dizzy. Safety first. Record the last completed stage and any partial. A valid test needs a plateau in VO2 or HR, but for home tests, just note your max RPE >9.
