Notes from the coaching floor

Nursing-home residents in their 80s and 90s built real strength and muscle under resistance training. Here's what that means if you think it's too late.

Gym lore says recovery falls off a cliff with age. The evidence is mixed, and your sleep and training history predict it far better than your birthday.

Your muscle comes back faster than it first built, but your tendons lag weeks behind. Here is how to ramp a comeback so your ego doesn't outrun the tissue.

After 45 a flat scale can hide fat gain and muscle loss at once. Why body recomposition beats aggressive dieting, and what the research shows.

Power drains about twice as fast as strength after 60. The reason sits in your fast-twitch fibers and the motor nerves that run them. Here's the physiology.

Deep sleep is when your body actually repairs muscle. Here is the recovery physiology, from growth hormone to overnight protein synthesis, explained plainly.

Older muscle needs more leucine per meal to trigger growth. Here is the threshold, why it climbs with age, and how to clear it across three or four meals.

Muscle isn't only for lifting. It's an organ that clears blood sugar, stores protein for illness, and signals to your bones. Here's how the mechanisms work.

Bone remodels only above a strain threshold, which is why walking maintains it but heavy lifting can build it. Here's the mechanism and the trials.

Lifespan is how long you live. Healthspan is how long you live well. The gap now averages about 10 years, and it responds to training.

Cardio isn't enough, lifting isn't dangerous at 90, and your metabolism doesn't crash at 40. Five longevity training myths and the studies that end them.

Your one-rep max won't save you from a trip, how fast you can make force will. Why muscle power, not maximal strength, protects against falls with age.
