Hollywood's biggest names were in award-worthy shape as they paraded down the Oscars red carpet last night. Some of the best bodies in attendance? Jessica Chastain, Viola Davis, and Cameron Diaz. The actresses shone in strapless gowns, highlighting toned arms and shapely shoulders. It was definitely a gentle reminder to myself that tank-top season is just around the corner, and that it's never too early to ramp up those upper-body workouts.
