How to optimize daily running and dumbbell training for a weight loss plateau under constrained home dietary conditions? Goal: I am currently stuck at 79 kg with a target weight of 59 kg. Current Situation & Exercise Routine: Weight: Stuck at 79 kg Daily Exercise: Running 1.6 km in 10 minutes every day. Available Equipment: Only 2kg ×2 dumbbells at home only. Nutrition Constraints: I am currently unable to fully control my meal prep or precise intake sizes due to living with family, resulting in higher-than-preferred daily caloric intake. Questions: Given that I already run 1.6 km daily, how can I safely introduce dumbbell resistance training to support calorie expenditure and body composition without overtraining? What are structured ways to progress this combined home routine (running + dumbbells) when further caloric reduction is currently limited by external dietary factors?
