Building a custom UI component library can be a challenge. Class Variance Authority (CVA) is a library that makes it easy to manage component variants. In this article, I show how to use CVA and Angular to build custom UI components. suleimanyunus.dev/learn-how-to-b…

Still overloading ngOnInit with all your component logic? 🤨 It's time for an upgrade. Tonight, we are joined by @divcenterer to dive deep into Angular Signals! Let’s look at how declarative reactive programming can completely clean up your codebase. Set your reminders below👇

@NyakegoMaponya Like “nah, ya’ll weren’t good enough” 😅

Do you know the pain of seeing the re-advert of a post you interviewed for?😭

@ronnieonly I definitely heard something like “Maelezo zaidi”

@rtwlz I want all of this just to say “Nothing on my end”

Okay, you post me on your Insta stories . I repost . Now why would you go and repost my repost?

@ChShersh My OCD has been triggered severely

I've just seen the worst enum in my life

@MetabolicUncle The paper disputes uniqueness, not value. That’s not the same as “waste of time.” Training decisions live under constraints: injury risk, recovery, adherence. Efficiency per minute means little if it costs consistency.

ZONE 2 TRAINING: A WASTE OF TIME FOR PEOPLE WHO AREN'T RACING A new analysis just torched the zone 2 hype. The conclusion? Current evidence doesn't support zone 2 as optimal for mitochondrial function or fat oxidation. This matters because the biggest health influencers have been pushing zone 2 as some kind of metabolic sweet spot. Turns out the data doesn't back that up. Not for regular people, anyway. Zone 2 gets defined as exercise where lactate stays under 2 millimoles per liter. That's the technical version. The practical version is the talk test: you can hold a conversation while moving. The supposed benefits? Better mitochondria and improved fat burning. Two things worth caring about, sure. But zone 2 isn't the magic bullet people claim it is. THE MITOCHONDRIAL MYTH Proponents say zone 2 builds mitochondrial capacity better than anything else. The evidence says otherwise. When researchers looked at the actual signaling pathways that trigger mitochondrial growth, zone 2 barely registered. Your cells need stress to adapt. Zone 2 doesn't provide enough stress. Not unless you're doing it for hours at a time, which most people aren't. One study found meaningful cellular stress from zone 2 exercise. After two hours. If you've got two hours a week total for exercise, spending it all in zone 2 means you're leaving serious gains on the table. High intensity work triggers stronger mitochondrial responses in less time. Multiple studies confirm this. A meta-analysis showed that for non-endurance athletes, zone 2 intensity didn't improve mitochondrial function at all. High intensity training did. THE FAT BURNING CONFUSION What about fat oxidation? The research is thin. One study found zone 2 training increased maximum fat oxidation rates after a year. A year. Other studies comparing intensities gave conflicting results. Some showed low intensity winning, others showed high intensity winning. A recent meta-analysis of 13 studies found both intensities improved fat oxidation equally. So zone 2 isn't superior for fat burning either. At best, it's equivalent to higher intensities. At worst, it's a waste of time you could spend on training that delivers multiple benefits simultaneously. THE REAL PAYOFF: VO2 MAX AND INTENSITY Here's what actually matters for health and longevity: cardiorespiratory fitness. VO2 max measures how much oxygen your body can use during intense exercise. It predicts mortality quite good, although it is debatable how influencers intepret the data. One study tracking heart disease patients for eight years found those with the best VO2 max scores had 84% lower mortality risk than those with the worst. The link between VO2 max and mortality crushes the link between mitochondrial health and mortality. And guess what increases VO2 max most effectively? High intensity exercise. Not zone 2. SPRINT TRAINING: THE EFFICIENT ALTERNATIVE You can trigger mitochondrial biogenesis with repeated sprint intervals. No need for hours of zone 2. Sprint protocols work in multiple formats. Ten seconds on, fifty seconds off. Or work-to-rest ratios of one to four with maximum thirty-second work periods. These short bursts create the metabolic stress your body needs to adapt. The beauty of sprint training? It improves mitochondrial function, increases VO2 max, and builds power. Three critical adaptations from one type of training. Zone 2 can't match that efficiency. It only puts stress on your body. Elite athletes do large volumes of zone 2 because they're already training twenty-plus hours a week. They need low intensity work for recovery between their high intensity sessions. They're optimizing performance for competition. That's not your goal. Your goal is health and functionality. Different objectives require different strategies. ZONE 2 CREATES STRESS TOO Even low intensity exercise loads stress on your body. It takes time. It requires recovery. If you're spending four to six hours a week doing zone 2, that's four to six hours you're not spending on strength training or sprint work. Both deliver better returns for longevity and function. Strength training builds muscle mass, which declines with age and predicts mortality independent of cardiovascular fitness. It improves insulin sensitivity. It strengthens bones. It makes daily tasks easier. Sprint training does all that plus maximizes cardiovascular adaptation in minimal time. THE PRACTICAL REALITY Most people struggle to find seventy-five minutes a week for vigorous exercise. The standard recommendation. If you've got limited time, zone 2 crowds out the training that matters most. The analysis authors acknowledge this. When you're not an elite athlete with unlimited training time, you need to prioritize efficiency. Focus on high intensity work done safely. Build up gradually to avoid injury. Include power training with heavier weights and explosive movements. This combination delivers the mitochondrial benefits zone 2 supposedly provides, plus improvements in VO2 max, strength, and power that zone 2 can't touch. If you've got extra time after hitting your high intensity targets, sure, add some zone 2. But for most people, that's a hypothetical. The reality is choosing between training methods. The data says choose intensity over duration. FUNCTIONALITY OVER ENDURANCE Can you sprint if you need to? This practical measure of fitness predicts independence in old age better than your ability to jog for an hour. Zone 2 training makes sense for ambitious athletes preparing for endurance events. Cyclists, marathoners, triathletes. People who need to sustain moderate effort for hours. If you're not racing, you don't need that adaptation. You need the ability to produce force quickly and recover from intense efforts. That comes from sprints and strength work, not steady-state cardio. The zone 2 hype reflects a fundamental misunderstanding of how to translate elite athlete protocols to regular people optimizing for health. Elite athletes optimize for performance within their sport. You're optimizing for longevity and function across all of life. PMID: 40560504

@GeromeDEV You know what, you are onto something 😅😅😅

When you are lazy about updating your Angular library to support upcoming versions 😅

@WillyAbuga The hub Karen has family restrooms and I think that is really cool. More public spaces should probably adopt that.

I have gone on dates with the little one a few times,However each time when it’s to time to use the washrooms, I am always confused; 1. Should I take her to the ladies 🤨 BUT it would be inappropriate for me to enter 2. Men’s ? What if that is confusing for her? HELP

@Dzaina I love out of the box designs 😍great stuff

Theres a satisfaction that comes with designing something and seeing it out there.
