Do you need to train heavy to build muscle? 💪 For years the mantra was you need to go heavy to build muscle. Or you needed to go heavy to stimulate large type II fast twitch fibers but go light for more reps to stimulate smaller type I fibers. But new research has challenged that dogma. Several meta-analysis have shown similar muscle growth with low loads vs high loads when set number is matched & proximity to failure is similar (PMIDs: 28834797, 35015560, 33312275, & 33433148). While muscle hypertrophy was not different between high and low load training, strength increased significantly more with high load training in all these meta-analysis As far as targeting fiber types, it becomes kind of irrelevant when you take an exercise close to failure because fiber types tend to be recruited in order from smallest to largest. So with high load training, small & large fibers get recruited quickly but you don’t do many reps. With low load training, you initially recruit smaller fibers but as the muscle fatigues it is forced to recruit the larger fibers as the exercise is taken close to failure. The net effect is that taking sets close to failure with high or low loads produces a lot of muscle activation and similar hypetrophy The take home is, do what you enjoy if muscle growth is the goal. Just make sure you train HARD & go close to failure (within a few reps) & do enough total sets. But if strength is a priority you’ll need to train heavy & be careful going to failure as it can impair strength gains From my first conversation with Andrew D. Huberman, Ph.D.

FIRST LOOK: Brand new Tesla Model Y Performance In this in-depth review, I dive deep into the refreshed 2026 Tesla Model Y Performance and explain why it's the best-value high-performance EV SUV on the market today! Key highlights of the new Model Y Performance: Aggressive new exterior design with updated front and rear fascias, carbon fiber spoiler (reduces drag by 10% and adds high-speed stability), and stunning 21" Arachnid 2.0 wheels with staggered tires for superior grip and stance Blistering performance: 3.3-second 0-60 mph acceleration, "Insane" mode for maximum fun, improved brakes, and sharp, agile handling with Sport/Standard ride modes Impressive 308-mile EPA range thanks to higher-density battery cells (better than the old Performance's 279 miles) First-ever Vehicle-to-Load (V2L) capability in North American Model Ys – up to 2.4 kW from the charge port for powering devices or camping gear Upgraded interior: Larger 16" high-resolution center screen with thinner bezels, carbon fiber décor, and the most comfortable Tesla seats yet (heated/ventilated with powered thigh extenders and perfect bolstering) Surprisingly comfortable ride quality and quiet cabin – no noticeable difference from non-Performance models despite the sportier setup Fully loaded for $57,490 (all options included except FSD) – incredible value compared to previous generations If you're considering a performance EV that combines insane speed, practicality, efficiency, and everyday comfort, this is it.

Elon Musk says steel killed carbon fiber on Starship at one-fiftieth the cost. Carbon fiber was supposed to be the future of rocketry. Lighter than aluminum. Stronger than steel. Trusted by every Formula 1 team. SpaceX picked it for Starship. "Particularly if you go for a high-strength specialized carbon fiber that can handle cryogenic oxygen, it's roughly 50 times the cost of steel." Then progress stalled. The autoclaves needed to cure the resin had to outsize every autoclave on Earth, and the team couldn't even produce a clean barrel section without wrinkles. Musk, watching the Mars timeline slip: "At this rate, we're never going to get to Mars. So we've got to think of something else." So he asked the question nobody at SpaceX had asked: "What about steel?" It became known as the **cryogenic stainless flip**. Musk, who had already shipped Falcon 9 in aluminum-lithium, broke with the textbook. "When you look at the material properties of stainless steel, full-hard, strain hardened stainless steel, at cryogenic temperature the strength to weight is actually similar to carbon fiber." Starship ran on cryogenic methane and oxygen. The airframe lived at temperatures that flipped steel ahead of carbon fiber. "You could smoke a cigar while welding stainless steel." After Musk made the call, steel weighed less than the carbon fiber version. Fifty times cheaper in raw material. Twice the heat tolerance. Half the heat shield mass. Musk, looking back: "In retrospect, we should have started with steel in the beginning. It was dumb not to do steel." What "obvious" material in your work is silently costing you the project?
