Rhea Durham & husband Mark Wahlberg at the Ted premiere

The fashion model can't keep up with her super-fit spouse in the gym and she prefers not to exercise with him.

Speaking at the world premiere of Mark's new action film '2 GUNS at the SVA Theater in Manhattan, New York City, she said: "He normally makes me throw up or cry. I can't do his workouts, but I try."

Although she can't handle Mark's regime, Rhea is always impressed by her husband's stamina and she can't believe the amount of pull-ups and sit-ups he does to maintain his super-ripped physique.

Speaking to the New York Post newspaper, she added: "Really, the stuff he does with his own body weight is the toughest ... the pull-ups!"

Rhea was joined at the premiere by Mark - with whom she has four children, Ella, nine, Michael, seven, Brendan, four, and Grace, three - and the pair were joined on the red carpet by Mark's '2 GUNS' co-stars Denzel Washington, who brought along his wife Pauletta Washington, Bill Paxton and James Marsden.
Other celebrities in attendance included 50 Cent, Karina Smirnoff and Robin Thicke and his wife Paula Patton.
