This has shown for the first time that human muscles possess a ‘memory’ of earlier growth - at the DNA level. Periods of skeletal muscle growth are ‘remembered’ by the genes in the muscle, helping them to grow larger later in life. And also related to this there is some research which says Epigenetic modifications are heritable so will pass them onto your offspring. There was a study on obese men who undergo weight loss surgery and how the weight loss affects their sperm's epigenetics.
