What does your current 5x5 routine look like?
What are your current working weights in each of those lifts? (Not 1RMs.)[/quote]
My routine is as follows, 3 days a week, non consecutive days.
I can squat 185 lbs for 5 reps, bench 135 lbs for 5 reps, and deadlift 225 lbs for 5 reps.[/quote]
I don’t think cutting at this point will bring you closer to your goals.
You have a lot of room to get stronger with where you are weight-wise. You don’t necessarily need to put on weight in order to get stronger and look better, but you do need sufficient protein to build that muscle and enough overall calories/energy to recover and grow.
I would focus on eating better (even more than you currently do), and just slowly pushing your bodyweight up. You’re eating to get stronger and to build muscle, not for the sake of putting on weight. If you’re getting stronger and you look better in the mirror and pictures, then you’re doing things right… regardless of what the scale says. I would suggest taking progress photos every few weeks, just so you can compare things better; memory can get fuzzy.
I would also think about adding some chin-ups into your routine, after your deadlifts, either supinated (hands facing toward you) or neutral (hands facing toward each other). From a physique standpoint, that will help your biceps and lats, and help you look broader at the shoulders over time. They’re also generally good at helping balance the shoulder joints.
