The instant way to get 22 percent stronger

An absolute lie.

Pay attention! If you’ve been mindlessly going through your workouts, you could be missing out on big results.

A new study in the Journal of Strength and Conditioning Research found that when people focused on a specific muscle during basic lifts—i.e. thinking about pecs during a bench press—they worked that muscle 22 percent harder.

Just because you work something "22% harder" does not mean you are getting 22% stronger.

You are simply using the capacity you already had.

Getting stronger means increasing your strength capacity.

This is bulls**t at its finest.

And reason not to believe the sources.

These folks and the media outlet are IMHO charlatans and irresponsible idiots/crooks.
