On 21 July 2019 in Władysławowo, he won silver during his third bodybuilding competition. Until then, he had competed twice in classic bodybuilding, but in Władysławowo he made his debut in extreme bodybuilding, up to 80 kg, and once again proved to be a versatile competitor.

The discipline he had practised until then—barbell bench pressing—is only seemingly similar to bodybuilding. The two disciplines differ most in terms of nutrition. Zbigniew Boczar is the first soldier in Poland to combine both disciplines, which appear similar but are actually quite different, and he ranks among the leaders when competing.
