I'd like to hear a more in-detail analysis from you why his training program is moronic and how exactly it contributed to his back problems. You'd have to wonder why Laine and half of the Finnish elite NHL players train under the same physics guru summer after summer if the training programs he devises are "moronic". Surely these millionaires have somewhere else to go to if the guy isn't qualified to understand how to train with a back problem.
Here is your exact list that contains "half of the Finnish elite NHL players"
2018: Mikko Rantanen Patrik Laine Lauri Korpikoski Joonas Järvinen Joni Ortio Jerry Ahtola Sebastian Repo Aleksandr Georgiev Sampo Ranta Kaapo Kakko Aleksi Anttalainen Oskari Siiki Ruben Rafkin Matias Maccelli
Every single other elite player has quit the group, for example Tomi Kallio, who has said that he's been doing better after doing his own training. Ristolainen quit the group, and for example two of the best local players ever have never even been to the group (M. Koivu and M. Kipprusoff) - even though they have been extremely well aware of the group (due to their pro brothers trying the group out)
Every single other good nhl player has quit the group, and for good reason - the training program is nothing like the programs that the best players use, in hockey or in other sports
If you would care to read up on the subject, you'd quite easily figure out that there are several aspects to the program, which are not found in any other training program that any high-level team sport athlete would use:
-absolutely zero aerobic training
-completely one-sided / monotonous program consisting of only anaerobic training, strength training etc
-months without any sport-specific training
-anaerobic training so often that even the "speed work" is not really speed work, just stuff done in a fatigued state
-a completely moronic application of block-periodization training models, forgetting the main thing about block-periodization: when concentrating on one aspect of training, you should maintain the others
-training blocks are wayy too long, which gives sub-optimal results even for the abilities they are trying to concentrate on
For example: you should never completely quit speed/strength/skill/balance training, even when you are doing 2+2 weeks of "hard" aerobic+anaerobic endurance training.
They have for many months during the summer (for many years) completely neglected important aspects of training: aerobic training, real speed training, skill training, transfering the general training to sport specific movements / patterns etc.
Even when doing a "strength training block" or a "muscle hypertrophy block", you should't completely stop the sport specific training
You will not find a single soccer/basketball star who forgets the ball for 3-4 months on their "basic condiotioning" cycles of the season. The same is true for the best players in hockey: you can check out Connor McDavids' training programs during the summer, and you can see that even while he has improved his strength levels, he has kept on doing easy aerobic work + skating at least 3 times a week.
Even in the same city, Turku, the trainer of the local pro club constantly has the players do light aerobic work etc.
If the program is "good", it sure is a wonder that they are the only ones training in such a manner
Mikko Rantanen is an exection among exections, the coach has said so himself in multiple occasions. His mother has been a sprint runner, he has quality genes. His siblings are good athletes too. Rantanen would have been faster, stronger + better much earlier if he would've done better training also in the summers in stead of that program.
(Although it must be stated that Rantanen probably has not exactly followed the program: the program does not include any aerobic running, and he has been filmed in a documentary doing it alone in the summer)
