Hey! I’m here in Minneapolis for Day 1 of the StrongFirst SFG I.
Today we're sharpening the blade with the kettlebell clean. The students are putting in the work, one rep at a time. Want to earn your SFG I? Come train with me in Denver this September. https://t.co/yd3aV0RlV4

Press strong. Then press strong again.

While the SFL is barbell-focused, the kettlebell remains a powerful tool for building strong, resilient shoulders.

Different tool. Same standard.
Strong is strong.

Summer sports are here.
But many young athletes are going from 9 months of sitting straight into practices, camps, and tournaments.
Most injuries don't start on the field—they start months earlier.
Learn how chiropractic care can help young athletes move better and stay healthy this season.

@realEstateTrent Exactly! It is a good deed done by you.

[Dr. Michael Hartle @DrMichaelHartle]

@realEstateTrent IMHO, it never hurts to ask, which is what you did. He should treat this request with respect, even if he does not wish to sell.

[Dr. Michael Hartle @DrMichaelHartle]

@realEstateTrent Exactly!

“What does not kill me makes me stronger.” — Not necessarily.

Russian coach, Andrey Kozhurkin, made a 50,000-foot observation on the two diametrically opposed philosophies of stimulating adaptation.

The traditional one is pushing to the limit: “What does not kill me, makes me stronger."

The alternative is to train to “avoid (or at least delay) the unfavorable internal conditions…that lead to failure,” or reduced performance.

Let us use strength training as an example. The majority of bodybuilders and recreational athletes use the first approach. They train to failure.

In contrast, strength athletes such as Olympic weightlifters and powerlifters follow the second approach. 1,000-pound squatter, Dr. Fred Hatfield, famously proclaimed that one ought to “train to success,” as opposed to failure.
The differences between the American and Russian powerlifting methodologies notwithstanding, both countries’ strength elites share the same conviction that failure is not an option.

In endurance training, the first philosophy represents the consensus. Coaches expose athletes to acid baths to improve buffering. This is what Arthur Jones from Nautilus called “metabolic conditioning” back in 1975.

We shall go the other way: anti-glycolytic training (AGT).

Our goal is to optimize high intensity dynamic exercise loading parameters for stimulating MT biogenesis in FT fibers—and do it at a lowest biological cost (minimal deamination, minimal H* driven ROS production).
