Karina Smirnoff and Mike The Situation Sorrentino Ab-Off

‘Dancing with the Stars’ Karina Smirnoff, whose partner Mike ‘The Situation’ Sorrentino has killer abs, must be feeling the pressure because she’s been working out at home with her favorite workout machine, the Kymaro Rhythm Rocker. Karina, who was been heard saying she is trying to keep up with his abs by doing double time on her machine, has also been known to have dance-offs with her dancing colleague Lacey Schwimmer with their Rhythm Rocker workouts.
