After doing around 8 months of bodybuilding routines with little gains I finally decided to switch to a powerlifting workout, StrongLift 5.5 by Mehdi, I am 178 cm tall, weight around 57.4 Kg.
Before this I had only done high bar squat and bench press. But after looking at the SL videos I found that my form was poor, e.g. I wasn't going parallel on squats, my shoulders were coming off in bench press, hell I wasn't even holding the bar properly (not on the palm).
After completing two workout days - I noticed lower back pain on first day, especially after the row, I thought my form was still not 100% and there has to be some soreness. It was better after a day of rest but the second workout of OHP and Deadlift brought the pain back. Although its better after a days rest, it has me worried.
I need to know how to prevent this pain in my next workouts, exactly what to look out for.
