I had L5-S1 discectomy and laminectomy in February 2019. I was warned to avoid back weighted squats and deadlifts. Been back in the gym 8 months and dropped the weight I gained and am doing good with machines and some body weight or light weight exercises for legs/glutes. But I really need to lift that booty. I'm doing light 20-30lb dumbell / kettle bell deadlifts and squats (learned proper form) and bridge thrusts with a 30 lb bar across my hips. But need other exercises to help lift the booty.... Has anyone had this surgery and found exercises that help and don't hurt?
