I need an intermediate strength program

I've been lifting consistently for about a year now.
I'm in need of a strength program that I can lift about 3 times a week
which will improve my athleticism for basketball and volleyball.
My stats are :
Squat - 260 / 1rep max
Dead lift- 290/ 1 rep max
Bench - 165/ 1 rep max

I've been on starting strength for six months and I stopped progressing.
I've also been on candito training 6 week program for 15 weeks but I'm sick of
working out 5 times a week with such high volume. It's getting dull and I had to reset my max couple of times.

Unless you are sub 150lbs those aren't intermediate lifts, if you absolutely can't progress anymore then I would switch but if there is a little progression able you will be better suited doing that.

you are not an intermediate. you are still a novice. stick with a novice program like ICF 5x5, Sheiko 29, or SL5x5. you will not reap the full benefits of an intermediate routine like madcow
