In reply to goldmember:
Most people avoid every day as it hinders muscle development by not having a log enough rest for your muscles to recover.
People tend to go for a split (a, rest, b, a, rest, b, rest, repeat) were a is arms, back shoulders, b is legs, chest abs (or what ever you fancy).
Personally I just do compound lifts when I can as they hit most muscle groups (back squat, dead lift, oly lifts.).
Searching for work out routines on the internet is a nightmare - so many also claiming different things, just go with one you feel comfortable with/ enjoy the most

That's all to build muscle.. If you do weights for 4-5 months you will put on some muscle mass, then cut down to abs with diet and cardio for a month or two before the wedding. At 77kg you might need 3 months diet to get down to having abs though.
Get enough protein and good luck!
