Where is it all Headed?

In the beginning of modern strength-training there was the Squat.
Then came the enlightenment that Squatting was bad for you. Knees and backs were breaking everywhere.
Next came the new wave of functional training. [Im still not sure what function bosu ball squats train, unless you spend your life on a ships deck ].
Then it was decided that squats were not actually bad. But you had to prepare yourself fully. Foam Rolling and Movement Quality were the new buzzwords.
Then someone said: "Shouldnt exercise make you move better?" And now some feel that the whole Movement movement has gone too far. Back to basics they say.
Squatting should improve your squat movement.
Its only a matter of time before the next "evolution" of training.

Here is my biased, personal opinion:
Do what works for you. Stretch if it helps you. Foam roll if it makes you feel better. Squat if it makes you stronger. The experts agree to disagree. You have to decide what you will accept, implement, and live with.
In the end, your progress is the yardstick of the effectiveness of your approach.
If you aren't going forward, maybe you should try foam rolling with a bosu ball. Or doing mobility drills on the monkeybars. Or zercher squatting every day.
In the end, it comes down to one person. You.
Don't be afraid to try the recommendations, but don't be afraid to strike out on your own either.
