When I work with athletes the system that I used is pretty much the same, regardless of the level. That is we do three whole body workouts per week, in one we emphasize the eccentric more, in the second we emphasize the isometric action and in the third we emphasize the concentric.
And a mesocycle includes 3 phases, accumulation, intensification, realisation.
We often include a 4th workout which is either hypertrophy work, technique work on the olympic lifts or prehab/rehab work.
HOWEVER the actual methods and loading schemes will vary based on the athlete’s level.
I’m writing a book on the system at the moment.
I normally look at an athlete proficiency in the weight room when deciding the appropriate methods and loadng schemes (which are divided into levels).
A simple approach to evaluate the athlete’s level and which methods he can use is to look at the strength level (each rep needs to be done with solid technique to count, it’s not such about numbers. If an athlete moves a lot of weight but with poor coordinaiton I will often downgrade him).
Here is how you can get an idea of the “resistance training level” of an athlete. Note that these numbers assume proper full range reps. A lot of athletes get inflated number by doing half squats, bounced bench presses and fishing rod deadlifts.
What you do is look at how an athlete is performing in 5 key lifts and you attribute points to his performance.
You then add up all the points to see his level.
For example, if he did:
Squat 1.65x his body weight (3 pts)
Power clean 1.15x his body weight (1 pts)
Deadlift 1.75x his body weight (3 pts)
Bench press 1.5x his body weight (3 pts)
Did 8 pull-ups (3 pts)
He has a total of 13 pts
Beginner = Less than 12 pts
Intermediate = 12-20 pts
Advanced = 21-25 pts
Is it perfect? No. But it gives me a good idea where I can start with when it comes to methods and loading schemes on each of the three main days.
