Three Ways To Get Strong Without The Gym

An antibody, a pill and a pair of robotic shorts are all chasing the same prize. One arm curl a day, three seconds long, already delivers a slice of it.

Up out of the chair.

A man in his eighties rises again, then again.

Soft shorts hold thin cables along his hips.

They tug as he stands… and he clears two more stands a minute.

Strength you pull on like clothing.

The Three Second Lower

Ken Nosaka’s team gave 39 students one arm curl a day.

Three seconds long, at full effort, and lowering only.

Four weeks later that group tested about 11% stronger. All the work added up to 60 seconds.

01 Hold a dumbbell you can just about lift.
02 Raise it with both hands, or with a push from your free hand.
03 Lower it with one arm, slowly, across three seconds.
04 That is the day done, one rep per arm.
05 Five days a week, and let the weekend go.

Six lowers a day beat 30 of them in one weekly bout. Little and often is the trick.

Muscle answers to the lowering

Three labs chase the same prize with a drug, a pill and a suit. The slow lower is yours for free.

// MuscleShield

Regeneron ran a trial called COURAGE on 599 adults. Each of them took semaglutide for 26 weeks.

On that drug alone, a third of the weight they lost was lean mass.

Then the team added two antibodies that block the brakes on muscle growth.

In that arm, 93% of the weight lost was fat. Total loss came to 13.4% of body weight. This is phase 2 work, so it sits years from a pharmacy shelf.

Thomas Burris built a molecule that makes muscle act as if it trained.

Mice on it ran 70% longer and 45% further. Fat mice shed 12% of body weight in a month, on the same amount of food.

They also put on ten times less fat than the ones left alone.

No person has taken it yet… and mice are not men.

A Heidelberg team built the shorts from the top of this page.

Ten adults wore them, mean age 78. Walking took 13.6% less energy with the suit on.

Chair stands rose by about two a minute, and each one ran 9% quicker.

Ten people is a thin sample, and the gains were measured in a lab. Still, the paper ran in Nature Communications in July.

Most muscle headlines come from a brand, not a trial.

I spend more than $20,000 a year on private research… the sort hedge funds pay for. Walled off from the public.

Then I read the paper behind each claim.

My own slow lowers run on a 20 kg dumbbell, two weeks in. One arm knows about it, and that is one man’s report.

Drugs and suits need trials and money. Your lower needs a dumbbell.

In one small trial the lead scientist said a 60-year-old memory came to test like a 40-year-old. Then a trial almost a hundred times bigger found the gain only in people who were short to begin with.
