that's not soley because of the epigenetic muscle memory: 1. you also already have the basics of lifting technique down - it takes some time to learn to squat properly. 2. you are comfortable with going to the gym and getting into the lifts straight away instead of spending the first few months on the treadmill. 3. you're probably knowledgeable about programs and the need for progression. this is all in addition to the epigenetic muscle memory.
