If you've seen Jaron Ennis on fight night or when he isn’t in training camp, the one thing you'll notice is his extremely muscular frame.

Fans and media members have a hard time understanding how he managed to make the 147-pound limit. But now, those days are officially over.

This past weekend, the 28-year-old made his junior middleweight debut a quick one with a first-round stoppage of Uisma Lima at Xfinity Mobile Arena in Philadelphia.

Although his promoter Eddie Hearn believes he'll be impossible to beat at 154-pounds, he's completely convinced the world won't see his best until heading up in weight once more.

"I think the perfect weight for 'Boots' is 160," Hearn told several reporters. "I think he can go there now and be in his absolute prime."

The former Ring and unified welterweight champion has nothing but big fights on his mind and made sure to call his shot after barely breaking a sweat against Lima.

In a perfect world, Ennis (35-0, 31 KOs, 1 NC) would next face Vergil Ortiz before taking on the division's reigning titleholders and every other big name housed in the weight class.

WBC interim beltholder Ortiz (23-0, 21 KOs) is their number one target, according to Hearn, provided he prevails in a tough headline challenge against Erickson Lubin on November 8.

Regardless of the opponent, Hearn is fully confident in the switch-hitting star but hopes the reprieve his body receives from fighting in a higher division is enough to keep him sharp.

It's not a given.

"He will be tight at 154," Hearn continued. "People think that when you move up in weight, all of a sudden it's easy, he's massive."
