and you wonder why you were flamed to start a log....
really, with the simple answers you get do you think these questions are worth asking?
but no, if the 5x5 is an appropriate program for you then box squats are probably not appropriate for you.
This question is just as much about you as "Is it okay to yell in the gym?"but its not about me, its about squats and if the two are replaceble and if anyone has done them.
