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)?

In: Biology

Answer 1

In terms of muscle growth, the best you can hope for is about a 2-little bottle size of muscle growth per year (distributed across your entire body). 6 weeks is enough time for moderate fat loss, but not muscle gain.
