Coco Austin is known for her voluptuous body, which she works hard for in the gym, and she showed off some of her impressive moves in a recent Instagram snap. Hanging upside down from a bench, Coco pushed out a set of inverted sit ups. The traditional move is made much harder as you try to fight against the resistance of gravity while trying to complete a sit up. 

The 34-year-old model and entrepreneur is a gym junkie, but even she admitted that "These inverted sit ups are no joke." Coco is always switching up her workout to keep things fresh, including pole dancing workouts, which she really got into while rehearsing for "Peepshow" in Vegas.
