Could Just 90 Minutes a Week Help You Live Longer?

When most people think about improving their health, they imagine early morning boot camps, six-day training splits, or somehow finding another ten hours in an already busy week.

The good news?

You probably need far less than you think.

Recent research has highlighted that around 90–120 minutes of strength training per week may be enough to significantly improve overall health, reduce the risk of chronic disease, maintain muscle mass as we age, and potentially help us live longer.

That’s right. Around 30–40 minutes, three times a week.

Suddenly, getting fitter feels a lot more achievable.

Why Strength Training Matters More As We Age

Many of us focus heavily on cardiovascular fitness, and rightly so. Your heart and lungs are important.

But there’s another piece of the puzzle that often gets overlooked:

Muscle.

As we get older, we naturally begin to lose muscle mass and strength, a process known as sarcopenia. Left unchecked, this can affect everything from:

• Balance and coordination
• Bone density
• Independence later in life
• Metabolic health
• Injury resilience
• Everyday activities like carrying shopping or climbing stairs

The old saying “use it or lose it” turns out to be surprisingly accurate.

It’s Not About Becoming a Bodybuilder

Whenever people hear the phrase “strength training,” they often picture huge bodybuilders lifting enormous weights.

In reality, strength training simply means challenging your muscles enough that they adapt and become stronger.

This could include:

• Squats
• Deadlifts
• Pressing movements
• Pull-ups or rows
• Carrying weights
• Functional movements performed in CrossFit classes

The goal isn’t necessarily to become the strongest person in the room.

The goal is to remain capable, confident, and independent for as long as possible.

The CrossFit Advantage

One of the reasons CrossFit has become so popular is that it naturally combines many of the things that support long-term health:

• Strength development
• Cardiovascular fitness
• Balance and coordination
• Mobility
• Power
• Community and accountability

Rather than spending hours deciding what to do at the gym, the programming is already taken care of.

You simply turn up, train alongside others, and let the coaches guide you.

And importantly, everything can be scaled to your current fitness level.

You Don’t Need to Train Every Day

This might be the most important takeaway from all of this.

Many people avoid starting because they assume they’ll need to commit to training five or six days a week.

The evidence suggests otherwise.

For most people, 2–3 well-structured sessions per week can deliver incredible benefits.

That means:

• Monday, Wednesday, Friday.
• Tuesday, Thursday, Saturday.
• Or even just fitting sessions around your work and family commitments.

Consistency beats perfection every single time.

What About Cardio?

Don’t worry, we’re not saying to skip your walks or weekend runs.

Ideally, a healthy lifestyle includes:

• Regular strength training,
• Plenty of daily movement,
• Some cardiovascular exercise,
• Quality sleep,
• Good nutrition.

The beauty is that these habits don’t have to compete with each other.

They work together.

What Should You Do This Week?

If you’ve been waiting for the “perfect time” to start, consider this your sign.

Ask yourself:

Could I realistically commit to 90 minutes a week?

Three 30-minute sessions.

Two 45-minute sessions.

One hour-long class and a couple of walks.

For most people, the answer is yes.

And if those 90 minutes help you:

• Feel stronger,
• Move better,
• Reduce your health risks,
• Keep up with your children or grandchildren,
• And maintain your independence for years to come,

then it might just be one of the best investments you’ll ever make.

Final Thoughts

We often think of fitness as something that’s purely about looking a certain way.

But perhaps the better question is this:

What sort of life do you want to be able to live in 10, 20, or 30 years’ time?

Strength training isn’t just about building muscle.

It’s about building a future version of yourself that’s capable, resilient, and ready for whatever life throws your way.

And the best part?

You don’t need to spend half your life in the gym to achieve it.

Sometimes, just 90 minutes a week is enough to start changing everything.
