My one thing with 5X5 SL is that I feel the first 8 weeks are so easy that I struggle to get motivated to go to the gym and it's not even a challenge.
Has anyone else had to deal with feelings of revisiting old ground and feeling frustrated you are not a patch on what you used to be? My life overall now is much better than it was in 2011, I'm just looking to try and get more enjoyment out of the gym if possible!
Take bigger jumps at the start of the program if you feel its going to be to easy, also dont overestimate it either as this will have the same result, frustration at failure.
Obviously you wont be starting with the bar again so pick a healthy baseline, maybe even jump in around week 6 so 65kg squats, 40kg ohp, 100kg DL, 55kg bench, 60kg row etc, get back in the grove and progress from there.
Have a goal in mind, what would you like to achieve? Early 30's is far from an age to say you've peaked.
