Stars' Summer Style

Eager to hit the beach like Mischa Barton? Kickstart your bikini workout with Ramona Braganza's 3-2-1 Method. Mix up alternating through three 10-minute cardio sessions, two 10-minute circuit sessions and one 10-minute core session back to back. "Since the workout combines cardio sessions with circuit strength training sessions it is time efficient and keeps you burning calories the entire workout," Bragazanza explains.
