I guess we'll part company on this one. There are many schools of thought that believe you should never go to failure. And even those that advocate failure reps, rarely advocate working every set in a session to failure. Among other issues, it can lead to CNS burnout. Additionally, if you believe in the concept of muscle memory, you're effectively training your muscles to fail, as it's the last thing they did. Lastly, consistently putting your muscles in a state where they are incapable of executing the exercise, will eventually lead to injury.They absolutely should. But, I guess it depends on goals.
I agree, form shouldn't be sacrificed. And I've never seen anyone maintain good during a failure rep. If you think about it, it's counter-intuitive; your muscles have failed, but you're able to move them in the exact fashion you wish? More likely, under the duress of muscle failure, you're no longer cognizant of your form breaking down. You may be the exception to the rule in regard to this.That said, NEVER EVER EVER EEEEVVVER sacrifice FORM for weight/reps/whatever.
