It turns out, thicker thighs may actually be the key to a long, healthy life.
Researchers have linked greater thigh strength and size to lower risks of heart disease, diabetes, cognitive decline and overall death.
The thigh muscles, including the quadriceps, are among the body’s largest and most powerful muscles. They power everyday movement while helping support and protect our joints.
Beyond supporting everyday mobility, strong thighs may serve a greater purpose - better overall health and a longer lifespan.
A five-year study published in The American Journal of Medicine examined the link between thigh strength and mortality in people with coronary artery disease (CAD), a condition in which plaque builds up in the arteries that supply blood to the heart.
Researchers studied 1,314 people with coronary artery disease, mostly men with an average age of 65, who had been hospitalized or undergone surgery for the condition.
Participants' quadriceps strength was measured using a dynamometer, a device that measures force, by having them push as hard as they could against it with their legs.
They then compared leg strength with body weight to see how strong each participant’s legs were for their size.
Several studies revealed that having big strong thighs may increase your lifespan
Researchers tracked the participants for the next five years, and during that time period, 118 people died from any cause, including 63 from cardiovascular disease.
The team discovered that people with 10 percent greater relative leg strength (leg strength compared with their body weight) had a 23 percent lower risk of death overall, and a 34 percent lower risk of dying from heart-related causes.
'Skeletal muscle weakness promotes exercise intolerance and physical inactivity. Reduced physical activity itself has been shown to be an independent risk factor for cardiovascular disease and frailty,' the study stated.
The research added: 'Importantly, resistance training can enhance muscle strength, muscle mass, and functional capacity.'
Thigh size may also protect against serious health problems. A 2020 study published in Endocrine Connections linked larger thigh circumference to lower odds of high blood pressure, particularly in overweight people.
Researchers recruited 9,520 adults aged 40 and older from a larger Chinese community. They measured both thighs and took the average circumference.
Participants' blood pressure was measured three times, with the average recorded. They were then split into three groups based on thigh size - small, medium and large - and had their blood pressure compared.
The rate of high blood pressure generally fell as thigh size increased, especially among overweight and obese people in the study.
Movements such as squats and deadlifts target the quads, hamstrings, and glutes simultaneously, and can help build muscle in the legs
After accounting for factors including age, waist size, smoking and medical history, researchers found that people with larger thighs had roughly 49 percent lower risk of high blood pressure compared to those with small legs.
A 2018 study even found that stronger legs in adults aged 60 to 85 were linked to better brain function.
The research, published in Journal of Lifestyle Medicine, evaluated 1,508 participants' leg strength using a dynamometer. After they were given a two minute cognitive test, where they matched specific symbols to numbers using a provided reference key.
The participants' scores were compared and researchers found that people with stronger legs performed better on the cognitive test.
To improve overall health and wellbeing, the best way to build thigh muscle is through strength training.
Compound moves like squats, leg presses, deadlifts and lunges can build muscle to support everyday movement, especially as you age. Aerobic exercises like cycling, walking and yoga can also improve flexibility, mobility and endurance.
