We talkin' bout practice? — Oh yes, we are.

Allen Iverson was back on the gym ahead of his debut with his team, 3's Company, getting himself in shape before the long-awaited BIG3 league tips off in June 25 at the Barclays Center in Brooklyn.

The 2001 NBA MVP and four-time scoring champion is seen drilling jumper after jumper in this promotional video, now with a less aerodynamic game at 42 years of age, but impressive nonetheless, as his ability to dazzle with the ball hasn't left him.

The Hall of Famer noted he feels like he's starting all over again and is now putting in the work and sweat prior to his first game against the Brian Scalabrine-led Ball Hogs come next Sunday.

Iverson is seen practicing the famed four-point shot from half-court, a shot that could prove to be a game changer in a three-on-three scenario.
