Arizona Cardinals defensive end Darnell Dockett is wasting no time getting down to business in the off-season. Last week, Dockett posted two videos of himself performing Explosive Sled Rows, which target the core and back to develop full-body strength and power.
The 33-year-old is practicing the move while wearing a training mask, which mimics air conditions at high altitudes, forcing its wearer to use oxygen more efficiently.
Check out Dockett in action in the videos below.
