Right now I'm doing wendlers 5/3/1 with a big focus on BBB (big bit boring). Its an intermediate strength program with huge focus on compound movements, but I've added additional volume isolation wise. Shit ton of weighted pull/chin ups, benching, squats, deadlifts, and over head presses. Basically I do 3 strength sets with weekly changes in rep schemes, and then 3-5x10 at a lower load for hypertrophy. It is kicking my ass, but I'm repping out massive weight and my strength has skyrocketed from following the programming correctly. Strength work is in 4 week periods, so week one is 3x5, week 2 is 3x3, week 3 is your 5 rep max, then your 3 rep max, then you go for a PR on a one rep, and week 4 is a deload, so I just do high volume to drive mass through hypertrophy.

It might be a little too much volume for anyone without a foundation of strength in my opinion, but SL 5x5 is a great linear progression program to build strength for beginners, and as long as you're eating ebough and staying consistent, 5x5 moving into 5/3/1 would be a great way to build strength and mass.
