Slight change in workout regimen

Ok, so I have been having some lower back pain. So, I will cut out deadlifting (both stiff-legged and regular deadlifts). I will replace my barbell stiff-legged deadlifts and my regular barbell deadlifts with lying hamstring curls and bent-over rows. So, my new workout regimen will look like this:

M,W,F
*chin-ups 3 sets, 6-8 reps
*dips 3 sets, 8 reps
*military press 3 sets, 10 reps
*lying hamstring curls 3 sets, 10 reps
*bent-over barbell rows 3 sets, 10 reps
*barbell flat bench press 3 sets, 6 reps
*Kettlebell snatches 3 sets, 10 reps each arm
*kettlebell swings 3 sets, 10 reps
*low ab, upper ab, and oblique exercises
*standing calve raises
*barbell squats 5 sets, 10 reps

5-6 days a week will I do anywhere from 30 minutes- 2 sessions of 60 minutes of low intensity cardio

*****I miss my sissy squats!!!! I will start doing sissy squats in a few weeks.
