Gregg Sulkin, 27, is in shape! The British actor was sweating it out as he did a variety of exercises outdoors in Los Angeles on Wednesday, May 20. Gregg showed off his insanely toned abs as he opted to go shirtless at a local park, including a jump rope routine, sit-ups, and push-ups! Clearly, his exercise is paying off, as his arm muscles looked totally jacked alongside his perfectly chiseled torso.
