Why You Need to Train on One Leg

Most people train their bodies as if life happens with both feet planted perfectly on the ground.

Two-legged squats.

Two-legged deadlifts.

Two-legged machines.

Two feet.
Equal pressure.
Perfect symmetry.

But that isn’t how you actually live.

You walk.
You climb stairs.
You run.
You step over things.
You turn.
You reach.
You catch yourself when you lose balance.

And almost everything you do in everyday life happens one leg at a time.

That is why I believe single-leg squats, single-leg deadlifts, balance work, reaches and hip thrusts should be staples of your training — particularly as you get older.

Not because they look impressive.

Because they teach your body how to control itself.

Single-leg squats: Can you control your own body?

A single-leg squat isn’t just a leg exercise.

It’s a conversation between your foot, ankle, knee, hip and core.

You have to create stability while producing strength.

You have to control your knee.

You have to keep your pelvis organised.

You have to maintain balance while lowering and raising your entire body.

And suddenly you discover something that a traditional squat can sometimes hide:

How well can you actually control one side of your body?

Strength isn’t just the ability to produce force.

It’s the ability to produce force under control.

Single-leg deadlifts: Strength meets coordination

The single-leg deadlift is one of my favourite movements for developing the relationship between your foot, hip and core.

You stand on one leg.

Your body hinges.

Your opposite leg reaches backwards.

Your torso moves forward.

And your body has to remain organised throughout the entire movement.

This teaches your posterior chain — particularly your glutes and hamstrings — to work while your body is balancing.

It also develops something incredibly important:

proprioception.

Your body’s ability to know where it is in space.

The older we get, the more valuable that becomes.

Balance isn’t an extra

Balance is often treated as something you work on when you’re old.

I think that’s backwards.

You don’t wait until you lose a physical capacity before training it.

You train it so you keep it.

Standing on one leg may look ridiculously simple.

Until you close your eyes.

Or reach.

Or rotate.

Or move your centre of gravity.

Balance isn’t simply about standing still.

It’s about your ability to control movement while your environment changes.

Reaches: Teach your body to move outside its comfort zone

Reaching exercises are incredibly valuable because they challenge your body to maintain stability while your centre of mass moves.

Reach forward.

Reach sideways.

Reach across your body.

Reach overhead.

Now do it while standing on one leg.

Suddenly your body has to figure things out.

Your foot responds.

Your ankle responds.

Your hip responds.

Your core responds.

Your brain responds.

This is movement intelligence.

You’re teaching your body:

“I can move without losing control.”

Hip thrusts: Don’t forget the engine

Then there are the hip thrusts.

If your single-leg exercises teach control, hip thrusts allow you to develop serious strength through the hips.

Your glutes are powerful muscles involved in extending the hip and helping you create force.

Strong hips matter.

They help you walk, climb, run, jump and generate power.

And as we age, maintaining strength through the hips becomes increasingly important.

But don’t just chase how much weight you can lift.

Learn how to feel the movement.

Control the position.

Own the contraction.

Build strength that you can actually use.

The bigger picture

This isn’t about having the biggest legs in the gym.

It’s about having a body that remains capable.

Can you stand on one leg?

Can you squat down and get back up?

Can you hinge without losing control?

Can you reach outside your base of support?

Can you generate power through your hips?

Can you do these things on both sides?

These are much more interesting questions than:

“How much can you bench?”

Because strength that only exists inside a gym isn’t the whole picture.

Real strength is being able to move through life with confidence.

Train for the body you’ll need at 60

Your 40s and 50s aren’t the time to stop challenging your body.

They’re the time to become smarter about how you challenge it.

You don’t need to destroy yourself.

You need to expose your body to the things you want it to continue being capable of.

Strength.

Balance.

Coordination.

Mobility.

Stability.

Power.

Control.

Train both legs.

Train one leg.

Push.

Pull.

Squat.

Hinge.

Reach.

Balance.

And build strong hips.

Because the goal isn’t simply to look fit.

The goal is to remain capable.

To be able to climb the stairs.

Walk across uneven ground.

Get up from the floor.

Carry your bags.

Play with your children.

Travel.

Hike.

Sail.

Explore.

And wake up one morning at 70 and still trust your body.

That’s what training is really for.

Don’t just train the muscles you can see.

Train the body you want to have for the rest of your life.
