@Alan_Couzens And correct me if I’m wrong, in this context, light activity can mean a stroll, making the bed, watering the plants. It doesn’t mean a Z1 run/ride.

It doesn't have to be hard, you just need to #KeepMoving throughout your day!

@Alan_Couzens What is your recovery between strides? If I’m running at low end of Z2 (117-118bpm) and do 30s strides building to close to but less than 5k effort (this is uphill so pace is weird), I get about a 10bpm spike and take about 60 secs at easy run to drop back below 120

Strides, when done correctly, shouldn't be long enough (or fast enough) to significantly elevate your heart rate. Shoot for... - Set cadence first - Progressively lengthen stride over ~10-15s - Gradually build to ~5k pace or a little quicker - Once you hit that pace, ease back down. These are neuromuscular, not energy system training. Just enough to keep the FT fibers awake & alive.

@hjluks 2/2. At the same time, arguments from mechanism rather than epidemiology are constantly used to vilify foods. Yes, vegetables are full of chemicals meant to kill things that eat them. Yet epidemiology tells us that avoiding veggies is not a path to health.

@hjluks Actually, isn’t it possible that you are both right? To some extent eating psyllium because you’re short on fiber is perhaps a sign that the rest of your diet is way too low on fiber. You shouldn’t need a supplement. 1/2

@Alan_Couzens A friend new to exercise told me she was “doing Norwegians.” I told her not to take exercise advice from anyone who uses “Norwegians” as a noun referring to anything other than a group of people. So seductive: short time investment and big return. Perfect fodder for grifters

"But my watch told me my VO2max went up when I started regular HIIT workouts..."

@hjluks If only you were following the right influencers, you would know that oatmeal is a poison anti-nutrient. That stuff will kill you! It might take 107 years to do so, but beware

Long ride. Long gym session. Huge bowl of oatmeal 😋😋 Fuel your burn

@hjluks Recommended to me by top pro climber. Great results for both of us. No surgeries for related issues (note to self: start using it again): theraband.com/products/flexb…

The good news: the natural history of tennis elbow is highly favorable. Most cases resolve on their own within 6–12 months. Your job is to load the tendon appropriately, avoid cortisone, keep doing the things that don't hurt, and be patient. Surgery is almost never needed. You very often just need to wait longer — and load smarter. Full breakdown + downloadable guide: howardluksmd.substack.com/p/why-does-my-…

Start here: isometric wrist extension holds. Elbow straight, arm extended. Place your opposite hand on the back of your wrist and resist as you extend upward. Hold 30 seconds at moderate intensity. Rest 1 minute. Repeat 8 times. Once or twice daily. Then get in to see a PT. And a practical hack: lift with your palm facing up whenever possible. It changes the load distribution at the lateral epicondyle. Coffee cup, grocery bag, everything. Sounds too simple. Works.

@hjluks @AndyRenfree I try to get every data-obsessed runner who can’t run without checking their something on their watch or their Whoop to read Andy’s essay on running by feel (pinned in his feed). Great essay with the ex phys PhD to back it up

@tomagain @AndyRenfree Done. Thanks

Training with DOMS, yes or no?

@hjluks @AndyRenfree I found myself posting my comment about recovery at 62 and thinking, didn’t I say this to Howard yesterday? And realized it was Andy and thought you should know of each other 😀

@AndyRenfree If not already doing so, @AndyRenfree and @hjluks should be following each other. I find your perspectives on fitness beyond the Go Go years complementary and valuable.

@StottGeorge @hjluks 100%. When young I was time limited, but now I am recovery limited, not time limited. The 18yo I mentor is baffled. Why do I spend so much time indoors when I have time to be outdoors. How can I still bury her for ONE day of talus hopping and scrambling, but not two?

@hjluks I’ve found out now I’m retired having the time to do more doesn’t necessarily mean I should do more

The older you get, the more expensive your mistakes become. One impatient jump in volume, one extra session before you've recovered, and you're sidelined for weeks... sometimes months. What bounced back in two days at 35 costs you a season at 65.

@Alan_Couzens To cue up one of your favorite softball topics: is high-intensity the same as fast? Is low-intensity the same as slow? 😀😀

"Why don't we do high-intensity early in the build?" Because high-intensity and low-intensity adaptations operate over different timeframes...

@hjluks Add intensive selection for human outliers to early strength training & you hit loads that never did or will have any evolutionary pressure. Worse in skiing where you add lever arms. FIS had to limit riser plates and ski radius b/c skiers were getting so many MCL/ACL tears

Moses Moody — Patellar Tendon Rupture: The Surgery Is the Easy Part!! Moses Moody, the 23-year-old guard for the Golden State Warriors, ruptured his left patellar tendon late in overtime against the Dallas Mavericks on March 24. He stole the ball, drove toward the basket, and went down without contact while planting to jump. He was unable to bear weight and was stretchered off the court. Surgery is scheduled. The patellar tendon connects the bottom of the kneecap to the tibial tubercle, the bony prominence just below the knee. It is the final link in the extensor mechanism — the system of the quadriceps muscle, the quad tendon, the patella, and the patellar tendon that allows the knee to straighten. When it tears completely, the knee cannot extend. The surgery is relatively straightforward, but it demands careful technique. A first-year resident can easily do this with supervision. The torn tendon ends are reattached to the patella using heavy sutures passed through drill holes in the bone or secured with suture anchors. The most important technical detail is tendon length: the repair must restore the patellar tendon to its native length. Shortening it — even modestly — causes patella baja, a pathologically low-riding patella that increases patellofemoral joint compression and leads to pain and stiffness that can outlast the repair itself. To protect the fixation and allow earlier rehabilitation, surgeons typically augment the repair with a heavy suture or cerclage wire looped from the patella down to the tibial tubercle. This offloads stress on the repair site during healing. With that protection in place, controlled range of motion and early weight bearing can begin sooner, which limits quad atrophy and stiffness and improves long-term outcomes. The rehab is where the real work happens. It’s a VERY LONG ROAD. Quadriceps atrophy sets in quickly, and rebuilding the capacity to absorb eccentric load during running, cutting, landing, and jumping at an NBA level takes at least 9-12 months. The established return-to-sport timeline is often 9 to 12 months, and many players take longer to return to their prior level of performance. Structural healing and functional readiness are not the same thing. Moody is 23. Aging biology is working in his favor. Whether he is fully ready at the start of next season is a question the rehab process will answer. But I doubt it. Why did this happen??? I don’t know. Players are so powerful… forces are so high. Maybe we are reaching the limit of what our tendons can withstand?

@AndyRenfree I’m 62. Big diff compared to 52. Huge compared to 32. That’s why I mention systemic fatigue. At 32: eat a lot, sleep a lot and good to go. Now if I’m sore it’s a rest day, not b/c of DOMS but b/c of the load that got me DOMS. If all I did was pull-ups, I could run w/ sore lats

@tomagain Multiple muscle groups. Ended up opting to rest. I don't recover as well as I used to!

@Brady_H I had Google translate this and, in brief, yes.

@Alan_Couzens We have never had such broad access to such good info, but it has never had to compete so fiercely with bad info. And endurance exercise is one of the least important areas where that is true (just finished Maria Ressa’s bio about opposing the Duterte dictatorship)

Please excuse my old man rant, but... We're losing our "real world" endurance training culture. It's being progressively diluted by polished lifelong "influencers" who keep spewing out popular but inaccurate information that has no basis in real-world experience. And every day it gets worse. It gets A.I. optimized for your audience to tell people what they want to hear. What they want to click on. And, so, every day we see more of this. More bullshit. And now, it's getting to the point that no one knows who the experts are anymore. No one knows what's real. Nowadays, the "experts" are those with the most articles, the most clicks. The fact that they've never trained an athlete in their lives? Doesn't matter. We've gone through 4 phases in my coaching life... 1/Real-world feet-on-deck, tyres on road, knowledge. 2/ Experts in the above coming together to share things in unpolished, but productive, ways on the interwebs - Glorious time. Absolute heyday! 3/ Polished "influencers" spawning at obnoxious rates and progressively replacing the real experts on the internet in the "content" they produce. 4/ That rate of 💩 increasing at rates never seen before thanks to A.I. ! Most of the real experts have retreated to caves somewhere by now. If you want to truly understand something about the things you're passionate about, go seek 'em out. Might be time for my morning nap.

@Brady_H I am not fluent in emoji. I have no idea what that means. LOL
