Why are you doing endless sets of biceps and triceps but then only 2 sets of squats and 2 sets of deadlifts? Bigger muscles need more time and effort. And this is especially true if you want to get strong. If you look at strength programs, they have set/rep protocols like 5x5, 6x4, 7x5, 8x4, 10x3, etc. 2 sets of 12 is not going to cut it.
If your primary focus is strength, then I would start each training session with a main lift (squat, bench, deadlift, overhead press). Second exercise will be a compound lift that is an assistance exercise to hit a particular weakness. Then the accessory work after that will be more single joint, hypertrophy typical bodybuilding style work. This should give you a nice balance of strength and size while bringing up any weaknesses you may have specifically. So a typical day could look like:
Back squat - 5x5
Beltless Front squat - 3x5
Leg curls - 4x10
Calf raises - 3x15
"Strength is the product of struggle, you must do what others don't to achieve what others won't."
Squat: 463 Bench: 275 Deadlift: 529 Total: 1262
"Technique is always the first place to begin when striving to improve at a specific skill."
