*To clarify, this isn't directed towards competitive O-lifters, as many already know this through experience and shared knowledge.
Maxing on Squats and Deadlifts Everyday. I really liked this article by Greg Nuckols. He gives a very clear and concise description to the often misunderstood Bulgarian Method of training: high frequency, high intensity training on a daily basis. Basically working up to a training max on a couple lifts everyday (or at minimum of 4-5 days per week). The program worked well for Greg, and I have witnessed to be very effective for one of our competitive Olympic lifters here at UND.
The details of the Bulgarian method are pretty straightforward, however the key point that I believe so many miss is as Greg stated:
"Here, the daily max is a weight that you can move without mental arousal (no death metal and ammonia) and without any aberration from perfect form."
The Bulgarian Method has been chastised by many lifters and coaches claiming the impossibility of maxing daily without the assistance of drugs. The problem is their definition of maxing is to think of testing/evaluation or competition day efforts. The type of efforts resembling borderline psychosis, training partners slapping each other on the face prior to each attempt, lots of yelling and chest beating... to the point that the whole pre-max attempt celebration and max attempt requires an automatic defibrillator to bring back to life the lifter and spotters. This can be fine at the right times (competition, evaluation at the end of a meso/macrocycle) but it will limit the frequency that one can train with high intensity, because it's not just the intensity (load and/or speed) of the work, but one's psychological state.
And this is often the crux of the issue. So few are aware enough to realize the amount of effort required for performance enhancements, while governing this effort 'to live to train another day'. Very few can find, nor understand, the optimality of arousal to elicit the desired outcomes of training. Excessive arousal will deplete energy stores and make a mess hormonally, and lethargy leaves everything to be desired. It's an amazing skill to be acquired to fully direct nervous energy yet still tempering the nerves. The goal is to minimize arousal and increase performance. Truly, the mind is the body and the body is the mind.
As I stated, high levels of emotional energy are ok at carefully selected times and with simple tasks (Yerkes-Dodson Law) - it's just difficult to sustain and very depleting. And when trying to improve a skill, hyperarousal and not sustaining a regimen will obviously make the acquisition of the skill(s) very difficult (in the case of a strength, power, or speed skill). There are no secrets, just a guiding and balancing of energy. I do believe the Bulgarian Method or more generally high frequency, high intensity training can be very effective, even without drugs (of course abiding by appropriate recovery ettiquite). It just takes an athlete or group of athletes with the right desire, action, and emotional intelligence: Stoicism
"When I see a man in a state of anxiety, I say, 'What can this man want?' If he did not want something which is not in his power, how could he still be anxious?" -Epictetus
And within that quote there is great insight into both an athlete's approach to training and a coach's approach to coaching that athlete.
