Running/Jogging

Running isn't really an exercise which will cause you to gain muscle mass. No exercise will really do that efficiently without your diet being conducive to that, and it's not easy to do even with a proper strength training routine. Running is a cardiovascular exercise, so it helps improve your heart and lung function, burns calories, and although you experience muscular adaptations when you begin running, the muscles don't really get bigger. The only way running might be a factor in some people gaining weight as it does make some people hungry, and then the temptation is to eat beyond just replenishing the calories you burnt off.

However, resistance training helps to retain strong muscles, which is helpful for running, so you may want to think about that too.

You're not going to gain huge amounts of muscle eating at a deficit regardless of what exercise you're doing.
