Jason Kelce was an absolute beast on the field. At 295 pounds during his final NFL season, the former Eagles center was built for battle: tough, powerful, and relentless in the trenches.
It’s been about a year and a half since he hung up his cleats, and now he’s showing off a very different version of himself. Kelce has shed 30 pounds since retiring, and the difference is hard to miss.
He looks leaner, noticeably more defined, but still strong, exactly the kind of post-career transformation we’ve seen from other former offensive linemen.
After years of maintaining bulk for performance in the NFL, many players, typically linemen, slim down once the constant eating and weightlifting routine slows down. But for Kelce, this isn’t about shrinking down completely.
Despite the weight loss, he’s sticking to a disciplined bodybuilding regimen, not to disappear, but to stay big, just in a different way. He’s shifted his focus from brute strength and blocking defenders to sculpting muscle and refining his frame. And it shows.
He’s trading in his NFL armor for a lean, muscular physique that proves he’s not done pushing his limits. Just because he’s off the field doesn’t mean he’s out of the gym.
Jason Kelce Seen Training with Dr. Mike Israetel
In his recent vlog, Jason Kelce trained with popular bodybuilding coach and YouTuber Dr. Mike Israetel, giving fans a raw and honest look at his post-retirement fitness journey.
While Kelce has dropped 30 pounds since his final NFL season, he made it clear that he’s not aiming to get small. “I’d like to lose weight but also remain big… but I also don’t want to weigh 295 anymore ‘cause there’s no benefit to that,” Kelce explained.
For Kelce, the goal is all about balance, shedding the unnecessary bulk while maintaining strength, muscle, and size. “I like feeling big and I like feeling strong, and looking strong,” he added, reflecting the mindset of many former linemen shifting from performance to longevity.
Coaching Kelce in hypertrophy training, Dr. Mike started the workout with incline bench press. Jason had to raise his chest higher to maximize muscle engagement and protect his shoulders. Kelce completed three working sets: 8 reps in the first, 5 reps in the second, and 4 reps in the third.
Next were inverted skullcrushers, a bodyweight triceps killer. Kelce pushed through 15 reps in set one, 13 in set two, and 10 in the final round, focusing on slow, controlled movement.
They followed up with deficit push-ups, three sets of 10 reps each, emphasizing full range of motion to build chest and triceps power. The session closed with lateral raises, totaling 25 reps, to hit the delts and bring out width in the shoulders.
Although this was not Jason’s complete routine, it did touch upon the foundation on which he will be approaching his post-NFL fitness journey: hypertrophy training, which focuses on increasing muscle size through targeted resistance exercises.
Kelce’s approach proves he’s not just staying active. Rather, he’s evolving. Retirement hasn’t slowed him down. It’s just changed the game.
