That sounds good mate!! You can ride starting strength till your close to a 300lb squat. Bill Starr can take you to around 400lb mark. By then you will know your body well enough to make your own routine, or at least make the correct changes to go in the direction you want . Good luck mate!
Hey mate!
If your after progressing past Starting Strength, you can do Bill Starr Intermediate 5x5, or even go to the Reeves Classic (full body routine). You can go onto a full body routine if you want. There are a lot of them around. What are your goals?
