Coming off a strong season, the first in his four-year contract extension with the Philadelphia Eagles, Brandon Graham is hard at work in the off-season. The 27-year-old defensive end is currently spending most of his time at Barwis Methods Training Center in his hometown of Detroit.

Graham recently posted a couple of videos to his Instagram showing off some pretty impressive lower-body strength. Check out the videos above (and links below) where he performs a “Pause Bear Eccentric Squat” with 735 pounds for 5 reps, then with 900 pounds for 4 reps.
