At just 23, Cooper DeJean has already etched his name into Philadelphia Eagles lore, none more vividly than his 38‑yard pick‑six in Super Bowl LIX that turned the tide against Patrick Mahomes and the Kansas City Chiefs.
Beyond the highlight reel, the Iowa native spends countless hours in the weight room, a deliberate choice to forge the raw power needed to match up against larger receivers and to deliver hits that echo through the secondary.
Training that turns preparation into performance
His regimen begins with Keiser squats, a movement he describes as a conduit for fast force production, allowing his legs to explode off the line with the same velocity he displays when closing on a deep ball.
Complementing the squats are depth‑to‑broad jumps, which sharpen his ability to cover ground in a single bound, and kettlebell plank push‑pulls that blend balance with control, enabling rapid direction changes without losing posture.
The full session also weaves in barbell back squats, medicine‑ball oblique iso holds, flying 20‑meter sprints and classic suicide runs, each chosen to target a specific athletic attribute — whether it’s rotational stability, acceleration or endurance.
DeJean says the combination of raw strength and refined agility not only prepares him for the physical toll of the NFL but also gives him the confidence to lock down receivers and disrupt offenses week after week.
