Wow. Scientists are now warning that the latest COVID variant could trigger a “heart failure pandemic.” And get this: Pfizer, the same company that sold you the so-called vaccines, is making a big bet on that “heart failure pandemic.” The pharmaceutical giant recently acquired several companies. This includes a major $6.7 billion cash acquisition of Arena Pharmaceuticals, a firm specializing in developing treatments, particularly for heart inflammation conditions like myocarditis and pericarditis. So, the company that caused the heart damage is now looking to profit from heart damage. Is my analysis wrong here?

The failure of FTX is not a failure of crypto, it is a failure of centralization. DeFi is the point.

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.

Muscle atrophy from hormone experiments is all fun and games until you remember that your heart is a muscle that has to keep beating as it's atrophying. This can cause structural remodeling of the heart (cardiomyopathy) contributing to the elevated risk of heart disease MTF transitioners have.

Please try and understand. This is not FAT LOSS that a little manipulation on the plate will get us results. If we want to BUILD PRECIOUS MUSCLE then we have to embrace hard work. We have to enter those zones of discomfort and penance. We have to train hard till failure. That’s the only way that works. We can’t expect to be pretty and proper. We have to Man Up
