Decades of sitting at  a desk can wreak havoc on your muscles.

And all his desk work, which may appear to be mainly work of the mind—reading and writing—also trains his muscles. Teaches his muscles how to be, or how not to be.

Sitting in a chair, he unconsciously teaches groups of muscles on the front of his body, flexor muscles, to tighten—including upper-body muscles that pull the arms and shoulders forward, such as the biceps and pectorals, and lower-body muscles, at the junction of the pelvis and legs, that pull the hips forward.

The pernicious engagement of those muscles—as well as disengagement of the opposite sets of muscles on the back of the body—helps explain why, after sitting for a while, he feels stiff and starts to ache.

“Left to its own devices, your flexors will tighten up and take you back to the fetal position, whence you came—if you don’t do something about it.”

So, before the sitting starts, Stocking tries to compensate for some of his extensor muscles’ impending deprivations.

The biggest muscle in the butt, the gluteus maximus, is a priority because it is the biggest, thickest, most powerful muscle in the body—and the significance of this muscle would be difficult to overstate.
No other mammal even has a gluteus maximus.

Stocking’s strategies for avoiding gluteal amnesia include the hip thrust. With the lower edges of his shoulder blades pressed against the side of a bench, a bed, or a sofa, and with his feet flat on the floor in front of him, his knees bent and his trunk muscles braced—to keep his spine in neutral position—Stocking extends his hips and contracts his glutes.

Stocking’s favorite exercise for the upper body is the row. His favorite form of the row is the reverse pullup.

It was like a revelation when chain-of-thought AI became viral news as a GitHub project that supposedly competed with SOTA's with only 2 developers and some nifty prompting...
Did all the companies just jump on the bandwagon an weave it into GPT/ Gemini / Claude in a hurry?
Did those companies already have e.g. Gemini 2.5 PRO thinking in development 4 months ago and we didn't know?

Hopping, a plyometric move, has been show to build power which translates to better running at higher speeds.

Six-Week Daily Hopping Program:

Week 1: 5 sets of 10-sec. hopping/50-sec. rest (total hopping: 50 seconds)
Week 2: 6 sets of 10-sec. hopping/40-sec. rest (total hopping: 60 seconds)
Week 3: 8 sets of 10-sec. hopping/30-sec. rest (total hopping: 80 seconds)
Week 4: 10 sets of 10-sec. hopping/20-sec. rest (total hopping: 100 seconds)
Week 5: 15 sets of 10-sec. hopping/10-sec. rest (total hopping: 150 seconds)
Week 6: 15 sets of 10-sec. hopping/10-sec. rest (total hopping: 150 seconds)

Painting a door might seem straightforward, but achieving a professional finish requires careful preparation and the right techniques. Whether you’re refreshing an old door or giving a new one a flawless coat, following these expert steps will ensure a smooth, durable result.

• Drill one 3/16-in. hole in the bottom of the door and two at the top, then turn 4-in. by 1/4-in. lag screws 1-1/2 inch into the door. Spread the sawhorses apart just enough so that the door doesn’t touch either side but rests entirely on the bolts.

• Clean Off Grime Before You Prime

• Fill All Holes, Even Small ones

• Prime the Entire Door Before Painting

• Search for Flaws After Priming

• Sand Between Coats (180 or 220)

• Use a Special Mini Roller (high-density foam)

• Protect Freshly Painted Doors From Sticking (masking tape)

Declan Chidlow takes us on a really interesting tour of the often, under-reported world of print stylesheets, how to use them and also how to debug them.

Physical, absolute units

When we’re writing CSS, we tend to use relative, responsive units such as rem, em, etc, which scale based on user preferences and such.
Sometimes, I find myself forgetting that CSS even has units of standard, absolute measurements, but we have a lovely collection at our disposal. It is worth keeping in mind they aren’t always accurate on screen, but they usually are when physically printed.
