In a series of videos on her Instagram Stories, the Big Bang Theory star balanced on a blue exercise ball, helped by some mobility sticks. The star kept it casual with her workout gear opting to go with some black sweatpants and a yellow T-shirt with some hearts on it that read Whatever I'll stay home with my dog. She uploaded three different workouts, which featured some alternating box steps and some walk-out push-ups. A final exercise saw her strapped into some gear as she attempted to lift one leg, remaining balanced on the other. Kaley Cuoco undergoes some incredibly grueling workouts to keep her physique, and in a new clip, she has shown off some seriously impressive balancing skills.
