In addition to the 5 sets of 5 reps for the 3 exercises (only 1 set on deadlift) you do 2 sets of 5 reps with an empty barbell. Then do a third warm set adding 25-45 pounds increments with just 3 reps. Then do a final warm up set of just 2 reps. http://stronglifts.com/5-rules-to-find-your-perfect-warm-up-weight/
Here is what I did in my "Work Sets"
Squats 5 set of 5 reps with 55 pounds
Bench Press 5 set of 5 reps with 90 pounds
Barbell Row 5 set of 5 reps with 105 pounds
(I was only suppose to do 100 pounds but I forgot my training info sheet)
This workout took me around 45min but I was just getting used to my warm up sets. Right now everything is fairly easy so I am putting my full focus on developing good form.
