A 19-Year-Old has sculpted an impressive physique despite his arm being paralyzed

Jackson has been trolled as a result of his image but that hasn't stopped him from hitting the gym. The teenager has taken all the jokes in good faith and even admits that he "loves" them. However, as reported by news.com.au, Jackson explained the perfectly reasonable explanation behind his unusual physique.
