According to TMZ, he’s flying celebrity trainer Gunnar Peterson to Paris to work out with him and Khloé Friday, Saturday, Sunday, and Monday.

Apparently Rob was training five times a week, but he had to slow down because of other commitments. Peterson said that he’s “the gatekeeper of Rob's workouts, not the gatekeeper of his life.”
