MLB infielder Hanley Ramirez is at it again—working out hard in the parking lot. Yesterday, Ramirez posted a video of himself performing five explosive sled rows.

Ramirez makes it look easy, but if you listen closely you can hear his exhales at the end of each rep.

The Explosive Sled Row develops full-body strength, specifically targeting the core and the back to help the whole body harness its power. For a bonus video, check out Hanley Ramirez’s Overhead Tire Pull, above.
