I trained using the Starting Strength Linear Progression for two months before jumping ship to 5/3/1 BPS because it allowed for slower progression, assistance work, and aligned better with my athletic goals. Towards the end of my LP I was still making progress with ease, but my lower back, especially in the squat, has always felt “suspect”.
My current template is pretty much vanilla BPS with a push/pull/core BW circuit at the end with no additional weighted movements.
My question is: what can I add in to strengthen my lower back? I don’t have access to a back raise machine, so would light, high-rep good-mornings suffice?
Any insight is appreciated.
