The Barbell Squat — The Most Important Exercise Nobody Does Anymore

A Movement You Were Born to Do

Watch a toddler pick something up from the floor. They do not hinge awkwardly at the waist, they do not bend forward with a rounded back, they do not reach and strain. They squat — cleanly, deeply, naturally, with perfect mechanics that most trained adults cannot replicate. The squat is not a gym exercise that the human body has to learn. It is a fundamental movement pattern that the human body already knows, and that modern life has slowly trained out of it.

By the time most people reach adulthood they have spent years sitting in chairs, shortening their hip flexors, tightening their ankles and abandoning the full range of motion that a proper squat requires. The exercise itself has not changed. What has changed is the body attempting to perform it — and the culture that would rather reach for a leg press than address the problem properly.

What the Squat Actually Does

The barbell back squat is the only exercise that comprehensively loads the quadriceps, hamstrings, glutes, calves, core, erector spinae and upper back simultaneously under meaningful resistance. No single machine in any commercial gym replicates this. The leg press isolates the legs but removes the core demand, the spinal loading and the balance requirement. The leg extension isolates the quadriceps but produces none of the systemic training effect that comes from moving a loaded barbell through a full range of motion with the entire body engaged.

The hormonal response to heavy squatting is significant and well-documented. Compound exercises that engage large muscle masses — and no exercise engages more muscle mass than the barbell squat — produce the largest acute testosterone and growth hormone responses of any training stimulus. This is not a marginal difference. A training programme built around heavy squatting produces a systemic hormonal environment that supports muscle growth, recovery and body composition improvement in a way that a leg press and leg extension programme simply cannot match.

The practical consequences extend far beyond the gym. The squat builds functional strength that transfers directly to daily life — standing from a chair, climbing stairs, lifting from the floor, moving through space with control and power. The person who squats consistently has better posture, stronger knees, more resilient hips and a more capable body in the widest sense. The leg press produces none of these benefits. It is not a bad exercise. It is simply not the squat.

The Problem With How It Is Treated

The squat demands respect. This is not a philosophical statement — it is a practical one. The exercise requires adequate mobility, sound technique, patient progression and a willingness to leave the ego at the rack. Most people do not offer it these things. They load the bar too heavy and squat half the depth that the movement requires. Or they go too light, perform a quarter squat and wonder why the effort produces nothing. Or they try it twice, find it difficult, and migrate permanently to the leg press where they can push a number that sounds impressive without ever moving through a range of motion that challenges anything.

The squat is hard. It is hard on the legs, hard on the lungs, hard on the mental resolve to descend to full depth when the weight is heavy and the instinct is to stop short. This difficulty is precisely why it works. Every exercise in the gym produces results proportional to the demand it places on the body. Nothing places greater demand than a properly executed barbell squat. Nothing rewards that demand more generously.

Personal — Two ACLs and 185 Centimetres

I am 185 centimetres tall. In squatting terms that means a longer range of motion, a greater mechanical demand on the hips and ankles, and a movement that looks different at full depth than it does on a shorter person. Tall lifters face additional challenges in the squat — the torso tends to lean forward more, the knees travel further, the descent is longer and the bottom position is harder to achieve and maintain. None of this is a reason not to squat. It is a reason to work at it properly.

I have also had two ACL reconstructions on the same right knee. The first rebuilt it. The second rebuilt what the first had left. Between and after both, the muscle loss in the right leg was significant — visible, measurable and frustrating. The squat was part of the rehabilitation path both times, not something to avoid. The exercise that people most associate with knee risk was, in my experience, a central component of getting the knee functional again. Done properly, the squat does not damage healthy knees. It builds the muscular infrastructure that protects them.

I still squat. I still love it. The goal at fifty is 100 kilograms — a number that is not about ego, not about comparison with younger lifters, but about what the body is still capable of doing if given the training to do it. At fifty, with two ACL reconstructions and a right leg that had to be rebuilt from nothing twice, aiming for 100 kilograms on the bar is not a modest ambition. It is the point. Never too late.

Mark Felix — The Miracle Man

Mark Felix was born in Grenada in 1966. He moved to Lancashire at twenty-three and spent his twenties as a dedicated bodybuilder. He did not begin competing in strongman until he was thirty-seven — an age at which most strength athletes are winding down rather than starting. What followed was one of the most remarkable careers in the history of the sport.

Felix competed at the World's Strongest Man eighteen times, becoming the oldest man ever to appear in the competition at fifty-seven years old in 2023. He holds world records in grip events and built a deadlifting reputation that made him virtually unbeatable in that discipline — at ages when his competitors were half his age. He worked as a plasterer in Blackburn throughout his career, training around manual labour with no specialist facilities, no team of scientists, no recovery infrastructure beyond hard work and consistency. He was known as The Miracle Man not as a marketing exercise but because his continued improvement defied every conventional expectation about what the ageing body can produce.

In 2022, aged fifty-six, Felix won the Masters World's Strongest Man. He won it again in 2023. He won it again in 2024. Three consecutive titles in the over-fifty category, each one demonstrating the same thing: that the body, given the right training and the right mindset, does not simply decline on a schedule. It adapts to what it is asked to do. Felix was asked to produce strength in his fifties and sixties, and it produced strength. The lesson is not that everyone can be Mark Felix. The lesson is that the ceiling on what is possible at fifty is considerably higher than most people bother to find out.

Why It Has Disappeared

The squat rack sits empty in most commercial gyms for reasons that say more about culture than about the exercise. The leg press is easier to teach, safer to supervise and produces a number — a load on the machine — that sounds impressive without requiring the technique, mobility and courage that a proper barbell squat demands. Social media finished the job the leg press started. An exercise that looks difficult, requires depth that does not photograph well, and cannot be performed with a weight that impresses a casual observer is not compatible with a culture of curated fitness content.

The fear of knee injury has also played a role. The same knees-over-toes myth that removed the sissy squat from gym floors pushed people away from deep squatting — despite the evidence that deep, full-range squatting, done correctly, strengthens the knee rather than compromising it. The quarter squat performed out of fear produces weak quads and unstable knees. The full squat produces the opposite. The exercise did not become dangerous. The people teaching it became less willing to teach it properly.

The result is a generation of gym members who spend significant time and money on leg machines and leave with thighs that are not as strong, not as well-developed, and not as functional as those produced by two or three honest sessions per week with a barbell on the back and proper depth. The squat rack collects dust. The leg press has a queue.

What Proper Technique Looks Like

Feet approximately shoulder-width apart, toes turned out slightly — the angle varies by individual anatomy but typically between 15 and 30 degrees. The bar sits across the upper back in a low bar position (rear deltoids) or a high bar position (upper trapezius) — both are valid, each with different mechanical implications. Take a deep breath, brace the core firmly, and descend by pushing the knees out in the direction of the toes while the hips move back and down simultaneously.

The depth target is at minimum the point where the thighs are parallel with the floor — hips level with or below the tops of the knees. Full depth, where the hips descend below the knees, is the goal for those with adequate mobility. A shallow squat is not a squat in the meaningful sense. It is a quarter movement that trains a fraction of the muscles at a fraction of the range where they are genuinely challenged.

Return by driving the heels into the floor and extending the knees and hips simultaneously — the ascent is the reversal of the descent, not a separate movement. Keep the chest up, the back braced and the knees tracking over the toes throughout. Breathe out at the top. Rest fully between sets. The squat cannot be rushed.

The Bragging Rights Are Real

There is an honest social element to the squat that no other exercise quite replicates. The bench press has its own mythology — everyone knows what you bench — but the squat carries something different. A person who squats genuinely, deeply, with a real weight, commands a different kind of respect in a weights room from someone who leg presses the entire stack. The squat cannot be faked. The depth either is or is not there. The weight either moves or it does not. It is one of the few exercises where the performance is transparent and the standard is absolute.

This is not about ego. It is about what the exercise represents: a commitment to doing the hardest thing properly rather than finding a comfortable approximation of it. The person who squats — really squats — has made that commitment. That is worth something, and in a training environment, it shows.

The goal is 100 kilograms. At fifty. After two knee reconstructions and a right leg that was rebuilt from zero twice. That is the target. It is not a boast. It is an answer to the question of what is still possible when the decision is made to find out.
