You could look Louie Simmons and try a Westside approach . He uses a lot of assistance exercises. You could try the safety squat bar. it sucks and feels a bit like a front squat.
Westside dynamic day is more like doubles and triples 50-70% rather sets of 5. . You would eventually try bands and chains too.
