NO. This is really bad advice. NEVER lift to failure. You will injure
yourself. Can you imagine a newby trying tto squat to failure. recipe
for a broken back. Or trying a bench press to failure - broken neck!

DONT DO IT.

How about qualifying this with never do it unless you are an experienced
weightlifter? With the exception of my shoulders and scapular area, I
almost always work to failure and have been for years while under the
tutelage of a very experienced personal trainer.

I'd say never do it until you've been working out a long time, are sure
you have correct form, and in most cases someone around to spot you.

OK, you know more about it than me. If you are an experienced
weightlifter who really knows what you are doing - there may be a
reason to lift to failure.
But this is a weigh****chers newgroup not a weightlifters newsgroup.
With respect you are probably the ONLY competitive lifter here!! For
the rest of us leaving one more rep in the bag is the thing to do.
