Can You Build Muscle, Get Stronger, and Improve Endurance at the Same Time?

You’ve probably been told it’s impossible.

That you can’t build muscle and run faster.

That trying to get strong while improving endurance is a waste of time.

That you have to “pick one goal and stick to it.”

There’s a grain of truth in that advice, but it’s not the full story.

Because with the right strategy, you can build muscle, get stronger, and improve your endurance at the same time.

The catch?

You probably need to be doing less than you think.

The Problem With “All-In” Thinking

Most people go wrong with concurrent training by going all in on everything at once:

• 5x/week lifting plan

• 40+ miles of running

• CrossFit metcons sprinkled in for “fun”

That’s not concurrent training.

That's being an idiot.

That’s a recipe for burnout, nagging injuries, poor recovery, and poor results across the board.

Why?

Because your body only has so much recovery capacity, especially if you're not sleeping like a baby and eating like an off-season bodybuilder.

What Concurrent Training Actually Means

Concurrent training simply means you're combining strength and endurance work in the same training block.

It doesn’t mean you’re trying to maximize all three goals (muscle, strength, endurance) at the same time.

Here’s what actually works:

• Pick a primary goal and support it with secondary goals.

• Use the minimum effective dose for the goals that are less important right now.

• Manage fatigue so your training doesn’t cannibalize your recovery.

For example:

If you’re training for a half marathon but want to keep your strength, you might lift 2x/week, focusing on compound movements and do 3-4 runs per week (with one hard effort and one long run).

That’s a realistic and effective concurrent setup.

How to Make It Work in Real Life

Here’s a simple framework you can use:

1. Choose Your Primary Goal
Which matters most right now, adding size, building strength, or improving your engine? You can support the others, but one should lead.

2. Lift Heavy (But Not Too Often)
Two to three lifting sessions per week can maintain or even improve strength and size, especially when intensity is high and volume is reasonable.

3. Zone Your Conditioning
Use Zone 1/2 cardio to build endurance and aid recovery. Add short bursts of Zone 4-5 work if your goal includes race prep or performance.

4. Fuel Accordingly
More training = more fuel. Don’t try to cut calories aggressively while pushing performance goals. You’ll spin your wheels.

5. Monitor Recovery
If your sleep, libido, motivation, or strength numbers start to tank, you’re doing too much. Adjust volume before intensity.

Final Takeaway

Yes, you can build muscle, get stronger, and improve endurance at the same time, but not to your maximum potential in all three.

The key is to structure your training around your current priority, maintain the others with just enough work, and cycle your focus throughout the year.

Call to action:
Take 2 minutes today and write down your current top fitness priority.

Then ask yourself: Is your training actually aligned with that goal, or are you trying to do too much at once?

Dial it in.

Train with purpose.

And over time, you can have it all.

Stay strong and fast,
