Okay so I have a ride 3 days a week to the gym.
Monday / Wednesday / Friday

The main question here is what sort of routine should I be on? And for how long should I continue with this?

I weigh 148 and I can rep out 135 for bench with a spotter. 115-120 with ease.
My squat is pretty weak you could say. I go ass to grass with around 150.

All my compound strong lifts are decent so I'm not sure if I should do 5x5 until I can put up more weight or do like a push pull legs routine.

ppl if three days is all you got imo.

my foundation consisted of 5x5, worked great for me. you will know when you're ready for something else.

Google "5/3/1 e book" read it see if you like it, try it

Thanks for the replies. I really want to stick with 5x5 to get my weight up but I get so bored so quickly with it. I'll look up a ppl and check out that 5/3/1 routine too.

Doing PPL for now. Any other opinions / feedback?

What are your goals?

yes its dumb. working every muscle group only every 7 days, whats the point.
do a full body workout, no volume will compensate for the lack of frequency in your plan.

Id squat at least twice in a 3 days a week template.

I want to look a lot more defined , and I want to be shredded. Strength training isn't that important IMO. The strength gains will come sooner or later I'm not in a huge rush
