weight: 158
bench: max? dont know. i do 3 sets of 10 reps (45+10)x2 plus bar regularly.
squat: max? dont know. i do 3 sets of 10 reps (45+10)x2 plus bar regularly.
deadlift: no clue.
curls: max? dont know. i do 3 sets of 10 reps of 30lb. dumbbells. regularly.

never tried to do max on anything as i have no spotter and i dont like asking the people in my gym.

any ideas on what routine works best for strength gains?
