Wanted to add this and mention that I have changed up my routine to follow Greyskull LP instead of StrongLifts. I don’t believe Greyskull has been mentioned here yet. Just like the SL app, I use the Greyskull app.
The main reason for the change is volume. I found my legs getting demolished squatting 3x a week doing 5x5. With Greyskull squatting 2x and doing 3x5 my legs are still hurting but much better for hitting my TR workouts.
