Run at a constant speed for an hour, run at a constant speed for ten minutes, and walk slowly for a few minutes. Will you lose weight and not gain muscle?
Long-term continuous "brisk walking" is the best way to lose weight without increasing muscles. It usually takes more than 45 minutes to start consuming fat. It is recommended to walk for 2 hours continuously. The fast pace here is equivalent to 2 steps per second. Whatever! Of course, walking fast means drinking more water. Water is a necessity for fat decomposition!
