Thank you for this clear and very practical piece! I really appreciated how you translated a complex and often abstract concept (muscle mass and longevity) into something readers can actually think about in concrete terms. Framing muscle not just as a performance metric but as a key determinant of metabolic health, resilience, and aging makes the topic immediately more relevant. What stood out to me most was the shift from aesthetics to function. The idea that muscle acts as a metabolic reserve, supporting glucose regulation, protecting against frailty, and contributing to recovery during illness, is an important perspective that still doesn’t get enough attention in mainstream conversations. One aspect that might further strengthen the piece would be to expand slightly on how to assess enough muscle in practice, whether through strength benchmarks, functional tests, or body composition measures, since that’s often where readers struggle to translate insight into action.
muscle strength and especially power, not just mass, are key determinants of longevity and cognitive resilience, likely through neuromuscular efficiency and neurotrophic signaling like BDNF. The emphasis on compound, moderately heavy resistance training performed with speed is well aligned with current data linking functional capacity to both reduced mortality and preserved brain structure.
What's the theory of why lower grip strength would actually cause increased mortality? I get that there's a strong association, but in the absence of a theory of causation, isn't advice to specifically train grip strength potentially Goodharting the metric?
This was excellent reading. As a woman in my 50’s who has lifted weights since I was 18 years old, resistance training is my favorite exercises. Post hip surgeries, I now do mostly bodyweight, resistance band and moderate dumbbell work. Something interesting we all need to consider as we are aging - if we don’t use it, we lose it. I recently started something called Expiratory Muscle Strength Training using a small breathing device designed to work the muscles of the upper airway, core and chest. I was shocked when calibrating my trainer - I could not generate anywhere near the force of my healthy 24 year old daughter. Here it was, evidence of my age related muscle loss that I had no idea was there. Same principle can be found in the pelvic floor (yes, men are affected by this too), the face and neck (all the snoring sleep apneic folks out there), posture (hello posterior chain, muted down every day with tech neck) and this is perhaps the creepiest of all - loss of intrinsic foot muscle strength leading to hammertoes, flat feet, other foot deformities (next time you are in the company of a bunch of sandal wearing senior citizens, just take a look at their feet and you’ll be starting your toe and arch exercises straight away!)
In addition to structured weight lifting and resistance exercise - I also incorporate novel resistance work into my day. Activating underused and novel muscles/nerves is a two-fer - you get the benefits of strength training and neuroplasticity. Novel resistance + neural demand = untapped gains in strength and brain health
Would it be better for bench press targets and leg press targets to also be adjusted for height? I feel like there's a huge difference between a 35-year-old 6'6" man and a 35-year-old 5'6" man shooting for 8 reps of 170 lbs on bench press.

This was an excellent and actionable read!

Does the “rows” include machine rowing or mainly refers to free weight/ barbell rows (if I’m saying that correctly)? Thank you.
