The best way I’ve found to get kids to call consistent cadence on eccentrics/isometrics is the basketball ref technique. Plus it keeps them engaged.

Michael Phelps went six years without missing a day of training. 365 days a year. Christmas morning, New Year's, Thanksgiving. People assume I made him do that. It was the other way around. 🧵

Fall sports are coming to an end. Of the high school seniors who are planning to go to college, a lot are on a legit s&c program and a lot are doing nothing for their physical development. That second group is probably going to learn the hard way that just because you were able to dominate against 15 to 18-year-olds does not mean you’re going to be able to do the same against 18 to 24-year-olds in college. Not to mention… you never want to be the weakest, slowest, less powerful or out of shape freshman, come testing in the fall. HS seniors… attack the weight room with a legit program!

Most people assume that bringing down blood sugar after a meal takes a real workout, something like a brisk half hour or a trip to the gym. The research says the amount of movement needed is far smaller than that, and when you move matters even more than how long. The reason sits in your muscles. When a muscle contracts, it pulls sugar out of the blood without needing insulin to open the door. The protein that carries the sugar in, called GLUT4, rises to the surface of the muscle cell in response to two separate signals, and muscle contraction is one of them. That is why movement lowers blood sugar even in people whose insulin works poorly, and why the effect shows up within minutes instead of after weeks of training. A 2026 trial tested how little movement it takes. Thirty adults came in on two evenings and drank a standard sugar drink with 75 grams of glucose. On one evening they stayed seated, and on the other they stepped up and down stairs for a single minute at whatever pace felt comfortable. They rated the effort 1.9 out of 10, barely more than sitting. In the hour after the drink, their blood sugar rose about 42 percent less after the minute of stairs than after sitting, and their total sugar exposure across the session was lower too. The researchers chose the evening on purpose, because the same amount of sugar pushes blood sugar higher at night than it does in the morning. One minute is right at the edge of what works, and it does not work in every situation. The same research group ran the comparison in the morning with bouts of 1, 3 and 10 minutes after the sugar drink. Three and ten minutes lowered blood sugar, while one minute did not come close to making a difference. When they repeated it after a real mixed meal of 650 calories, one minute did help, trimming the blood sugar rise by about 14 points on a standard glucose meter. So a single minute seems to be enough after a normal meal and in the evening, but not reliably after a morning sugar drink. Three minutes worked in every version they tested, which makes three the safer number to aim for. Timing turned out to matter more than length. A 2023 analysis pooled eight trials with 116 people, about 4 in 10 of whom had type 2 diabetes, and compared exercising before a meal, after a meal, and not at all. Moving after the meal beat moving before it and beat doing nothing. Moving before the meal worked no better than sitting still. The analysis also found that the shorter the gap between finishing the meal and starting to move, the bigger the benefit, so a short walk taken right away does more than a longer one taken an hour later. The useful change is in the ten minutes after you finish eating. Sitting down is what most of us do by default, and for blood sugar it is one of the weakest choices available. Climb the stairs if you have them or take a walk if you do not, and keep in mind that starting sooner matters more than going longer.

Barry Sanders, Reggie Bush and Herschel Walker aren’t available. You need 200 rushing yards to win a national championship. Which college running back are you trusting?

The first ~6 weeks of strength training are mostly neural. After that, the structure of the body starts to change. What heavy loading does to muscle, tendon and bone 🧵👇

Vitamin C completely prevents rise in cortisol in stress study. More evidence for the anti-cortisol / anti-stress properties of high doses of vitamin C. Animals given a 500-700 mg human equivalent of C had no elevation in cortisol in response to stress. The adrenals concentrate vitamin C more than just about any other tissue, and appear to use it to regulate cortisol synthesis.

I really hate how many female athletes tear their ACLs in basketball/soccer
