Eli5: How much can a person transform their body like some work out programs claim such as “6 week body transformation”?

Question

Is it even possible (excluding the fact if someone does nothing but work out or work out for hours every day)?

Answer 1

I’ve done P90X a couple of times. Workout for 90 days. I did this with my wife and we both got pretty toned. I don’t remember starting/ending weights, but I’d say we both started we were in a spot where we could/should lose 20 pounds. Just for reference.
