How people get it: Free or low cost, at home, in a gym or in a class.
The basics
What it is
Strength training is exercise that makes muscles contract, often to lift a heavy object against gravity.

How it's thought to help
Slowly adding more weight, sets, repetitions, or days of exercise each week results in stronger muscles.

What people use it for
Muscle-strengthening activities are used to improve physical function and help people stay independent. They are also used to keep existing strength, slow muscle loss, and help prevent falls and related injuries.

What the research has found so far
On strength training and aging, PubMed lists 3,270 trials in people, 1,210 studies that watched people over time, 122 animal and lab studies. See the counts and searches
Stage 4 because it is recommended in the US Physical Activity Guidelines for Americans (muscle-strengthening activities on 2 or more days a week). See the source ↗

Side effects and risks
Overdoing strength exercises can cause exhaustion, sore joints, and muscle pain or injury.

Questions to ask your doctor
- Is strength training a good fit for me, given my health and the medicines I take?
- Is there anything I should avoid or watch for, given my health conditions?
- Where should I start, and how much is right for me?
- How would we tell whether it is helping, and when should we review it?
This is general information gathered from the sources listed, not medical advice. Talk to your doctor before starting anything new.

What others are writing
Recent articles about Strength training from health journalists, hospitals and universities. We link to them; we don't write or endorse them.
Strength training over decades linked to longer life ↗
“Researchers analyzed three major studies involving 147,374 adults (79% women) who were middle-aged or older at the study’s start and tracked for up to 30 years.”
Strength training for up to two hours weekly over decades is linked to lower risk of dying from heart disease and neurological diseases.
Moderate amount of strength training each week could boost longevity ↗
“Roughly 90-120 minutes of strength training per week was linked with a 13% reduced risk of premature death, according to a new study from Harvard T.H. Chan School of Public Health.”
A Harvard Chan study links 90 to 120 minutes of weekly strength training with a lower risk of early death.
Resistance training may boost longevity. But how much do you need? ↗
“Science shows that regular strength training —whether it be weight lifting or other forms of resistance work—can boost mental health, stave off disease and increase bone and muscle mass, all of which adds up to a longer, healthier life .”
The article says regular strength training may extend lifespan, and asks how much of it is needed for those benefits.
