The 26-year-old Rennes striker has visibly gained muscle mass, with his triceps now visible, as described by his former teammate and ex-defender Marc Laurent.
Lepaul has been following a specific strengthening program since joining the club, which has helped him to bulk up.
This physical transformation has been evident in his performances on the pitch, including a notable celebration after scoring the third goal for Rennes against Le Mans on August 30, which earned him a yellow card.
Lepaul's physical development is a significant improvement from his time at Lyon during his youth and even before joining Rennes last summer.
He will be in action this Sunday when Rennes face Angers at 17:15.
