Lester Martinez Prepares for Luka Plantic with Terence Crawford's Guidance

Iron sharpens iron. Boxing lives off that line, but every so often you see it in its purest form.

In a hot, unforgiving gym, the WBC interim super middleweight champion Lester Martinez is learning the hard way from a man who has already mastered the sport. Terence Crawford is back in the ring – not chasing belts, but shaping someone else’s.

This is not a nostalgia tour. It’s a live-fire tutorial.

Crawford steps in, the room changes

M Martinez defends his title on August 29 against Luka Plantic, a heavy-handed challenger who comes forward with bad intentions. To get ready for that kind of threat, Martinez hasn’t just hired a name. He has invited one of the best fighters of the last decade to punch him, prod him, and correct him.

And when Crawford walks in, everything tilts.

"When Terence steps back into the gym, the whole energy shifts. He doesn’t just watch; he breaks down moments, tells you where your feet should be, and shows you how to dictate tempo. Having a fighter of his caliber in your ear gives you total confidence."

That’s not a motivational poster. That’s a champion talking about another champion dissecting his every move. Crawford has always been a master of small details – the half-step, the angle, the pause before the counter – and he’s feeding those pieces to Martinez one bite at a time.

The lesson is simple: control the ring, control the fight. Against a puncher like Plantic, that can be the difference between a highlight reel and a nightmare.

Plantic calls it fear. Martinez calls it something else.

On the other side, Plantic has tried to turn Crawford’s presence into a psychological weapon, accusing Martinez of bringing in the American star out of fear. It’s a classic ploy: question the champion’s courage, seed doubt, tug at his pride.

Martinez isn’t biting.

"He can say I brought Terence because I’m scared, but on fight night, it’s just the two of us. He’ll realize very quickly that training with the best in the world wasn’t out of fear—it was out of preparation to destroy him."

That edge in his voice is backed by a résumé that doesn’t scream hesitation. Martinez went to war with Christian Mbilli and came out with a draw. Mbilli now heads into a blockbuster clash with Canelo Alvarez on Halloween. That’s the level of company Martinez has already kept. Quality of opposition is not the question here.

The question is whether he can refine the chaos.

BoMac’s blueprint: power with purpose

Trainer Brian "BoMac" McIntyre has seen this before. He helped turn Crawford from a gifted switch-hitter into an undisputed, pound-for-pound force. Now he’s applying that same demanding standard to Martinez.

The Guatemalan doesn’t need help finding power. He’s a natural knockout artist, a fighter who knows how to sit down on his shots, drive through his legs, and keep the whole kinetic chain firing when he lets his hands go. The danger is that raw aggression can spill over into waste – too many big shots, not enough thought.

"BoMac doesn't let you get comfortable. Every round in sparring has a purpose; every drill has a counter. We built a strategy specifically to neutralize Plantic's aggression and turn his momentum against him."

That’s the core of this camp: not just hitting harder, but hitting smarter. Not just surviving Plantic’s pressure, but using it against him. Every round with Crawford, every instruction from McIntyre, pushes Martinez toward that balance between violence and calculation.

Learning under fire

Crawford’s presence turns routine sparring into an examination. He isn’t there to nod and clap; he’s there to apply pressure, to force decisions, to make Martinez think at championship speed. It’s teaching under stress, with punches attached.

For a defending champion, there’s no better rehearsal. You don’t just pick up tricks from an undisputed great. You absorb habits, rhythms, standards.

On August 29, there will be no Crawford in the opposite corner, no BoMac shouting corrections between rounds. It will be exactly what Martinez said: just the two of them.

Then we find out if these weeks with one of the sport’s modern masters were a luxury—or the edge that keeps his belt right where it is.
