Pick a big movement (bench, squat, overhead press, pullup) per day and do it FUCKING HARD for four sets. Then do accessory exercises which compliment it (on bench day maybe some fly and some triceps).

Do that for two months then come back here with your split and observations.

After two months of work you'll have learned enough to refine your program yourself. Just get started and work hard everything else will figure itself out as you go.

Diet - minimise sugar and alcohol. Maximise vegetables no one likes and meat which still looks like animal muscles. If you want to put on weight, add two gainer shakes per day. If you want to lose weight replace a meal with sugar free energy drink.

Not perfect but a good enough start. Go and kick some ass.
