Clinical Context & Quora Fitness Discussion

Based on umbrella review data (PMC7357372; 179 primary trials), treadmill exercise robustly increases VO2 max across continuous (MICT) and interval (HIIT) training. Quora participants noted that low walking speeds without incline yield minimal cardio elevation, whereas 4+ mph combined with moderate-to-steep incline (up to 15°) drives substantial heart-rate response and outdoor-equivalent adaptation.
