There is no reason to change your current program. The best program for you is the one that you can stick to consistently. However, with consistent lifting, proper recovery and proper form, you'll find your max in every lift in about 5-6 months. As a beginner, you'll get strong, and build muscle in that program. Once you hit that plateau, it'll be mentally very tough to stay that way without changing your body weight. After all, more muscle means more strength when training properly.
