What exercises should i do at the gym to correct winged scapula and rounded shoulders?

Hi, what are some exercise you would recommend to open up the chest to help with rounded shoulders and for winged scapulas. i suffer from both, not in serious way like in the pic but when im bare chested i always have to remember to "force" my shoulders back, and i had these conditions since i can remember. Im planning on getting back at the gym after a 3 months stop and im looking for some exercise to include in my new routine. Thanks in advance :)
