I'd recommend reading through this article and trying the 5-3-1 program. It's simple and doesn't involve anything too crazy. I would just add some finishers to the end of each lift day like pullups, sprints, med ball slams, etc. After you complete that you can start a different program depending on what you want to focus on. I always recommend trying an intense squat program to anyone who hasnt tried one if they want big gains. http://www.muscleandstrength.com/workouts/hardcore-look-at-jim-wendlers-5-3-1-powerlifting-system.html
