Yeah, 5k in 25 minutes is by no means an easy jog for most people, and places OP in the average race pace, according to https://www.verywellfit.com/what-is-a-good-time-for-a-5k-291... (grain of salt, but they have more data than I do). Mind you, I interpret OP to mean that this is their current workout routine, after their dramatic weight loss and increase in fitness.
This is my current fitness level. When I first started going to the Gym I was averaging 2.5 km in 30 minutes. I should also add that I was a heavy smoker.
Nowadays, my routine consists of 5 different exercises and 25 minutes of running but I am not looking to break a record or become completely ripped. Just toned. So when I say that it is not too intense, I mean it as of now. When I first started, the workouts were a pain but I finally got used to them after a while.
