Yes — and the benefits go well beyond what you can see.
Running improves your heart and lung fitness, your energy, your sleep, and for a lot of people it does as much for the head as the body — stress, mood, and that sense of having done something good for yourself. Those are the changes people tend to feel first and value most.
One honest note: if your only reason to start is changing how your body looks, running alone is an unreliable tool for that, and it's a fragile motivation that tends to fade. The people who stick with it long-term are usually chasing how it makes them feel — stronger, clearer, more capable. Aim for that, and the health benefits come along for the ride.
