Here it is — the extremely first video footage of Lamar Odom training for his highly-anticipated star boxing match … and the man appears like he’s prepared to go!!

TMZ Sports broke the story … the 41-year-old, 2-time NBA champ has actually tattooed a handle Celebrity Boxing to enter the ring this summertime at the Showboat Casino in Atlantic City, NJ.

While LO’s challenger hasn’t been revealed (yet), it hasn’t stalled the man’s preparations … partnering with big-time fitness instructor Xavier Biggs to assist him prep for the fight.

In the video footage — gotten by TMZ Sports — Odom is seen dealing with his jabs … which might look like basic exercise things … up until you hear the noise he makes when his gloves struck the mitts.

FYI — Biggs is the go-to man for stars like Kevin Hart and Usher … so whoever’s breaking the previous Laker has their work cut out for them. After all, have you SEEN Kevin Hart recently?!

Of course, Odom is the very first NBAer to take the ring considering that Nate Robinson got knocked out by YouTuber Jake Paul … and we’re presuming he’s hoping it winds up much better for the hooper this time around.

While Celebrity Boxing’s Damon Feldman has yet to make Odom’s challenger authorities, we’re getting word it’s a MAJOR home name … however who understands, after seeing this video footage??
