Is your goal to gain strength in the big three? If so 1 month is a SHORT time to think about progression. Esp with a horribly programed layout such as yours. If your goal is to gain strength pick something easy to start like 5/3/1 and run it for 6 monthes to a year. Id prefer a year at the very least. Next step would be to buy the 5/3/1 book, yes buy the book. Also you may wanna not think about sessions as muscle groups but as movements since hypertrophy is in muscles and strength is in movements.
