Mark Wahlberg [1] stopped by The Ellen DeGeneres Show on Thursday and ended up working up a bit of a sweat. The actor helped raise money for Breast Cancer Awareness Month by doing as many pull-ups as he could in 30 seconds. Mark, who also talked about his "hairy ass" on the show [2], obviously killed the challenge and even put Ellen in a trance with his impressive muscles. Watch the clip above to see how many pull-ups Mark was able to do, and then check out his hottest Marky Mark pictures [3].
