One of the most common questions future Navy SEAL candidates ask is:
“Do I need strength training for BUD/S?”
The short answer is:
Yes.
The longer answer is:
You need strength, but you need endurance even more.
Many young athletes make the mistake of thinking BUD/S is a bodybuilding competition.
Others make the opposite mistake and become endurance athletes with no strength.
Both approaches can lead to failure.
The candidates who perform best are usually well-rounded athletes with a balance of strength, endurance, work capacity, durability, and mental toughness.
Why Strength Matters at BUD/S
Let’s clear something up immediately.
You absolutely need strength.
During BUD/S you will carry:
- Inflatable boats
- Telephone poles (logs)
- Scuba tanks
- Rucksacks
- Ammunition cans
- Your teammates
Strength is necessary for performance and injury prevention. Even official Naval Special Warfare guidance recommends developing muscular strength while avoiding excessive focus on adding mass.
If you are physically weak, every evolution becomes harder.
Boat carries become miserable.
Log PT becomes a nightmare.
Buddy carries become exhausting.
Strength matters.
Why Endurance Matters More
Now for the part that surprises most people.
The majority of BUD/S is not a max-strength event.
It’s an endurance event.
You run.
You swim.
You paddle.
You carry equipment.
You move for hours.
Then you do it again the next day.
And the day after that.
Experienced candidates and former operators consistently point to running and swimming performance as some of the biggest predictors of success during the pipeline.
The athlete who benches 315 pounds but struggles with a four-mile sand run is going to suffer.
The athlete who can run, swim, recover, and still carry his share of the load often performs much better.
The Biggest Mistake Candidates Make
Before I went to BUD/S, I trained like a bodybuilder.
Big mistake.
I spent too much time lifting weights and not enough time building endurance.
I looked strong.
I wasn’t prepared.
BUD/S exposed that weakness quickly.
Many candidates still make this mistake today.
They chase bigger bench press numbers.
Bigger squats.
Bigger arms.
Meanwhile their run times suffer.
Their swimming suffers.
Their recovery suffers.
Extra muscle that doesn’t improve performance becomes dead weight.
Strength That Transfers to BUD/S
The goal isn’t gym strength.
The goal is useful strength.
Ask yourself:
Can you carry a sandbag for a mile?
Can you ruck five miles?
Can you perform pull-ups after a long run?
Can you carry your buddy when exhausted?
Those questions matter more than your bench press.
Functional strength and work capacity translate much better to BUD/S than bodybuilding-style training.
The Best Strength Exercises for BUD/S
Sandbag Carries
One of the best exercises available.
Builds shoulders, traps, grip, core, and mental toughness.
Pull-Ups
Arguably the most important upper-body exercise for candidates.
Aim for 15-20 strict pull-ups minimum.
Walking Lunges
Builds leg endurance and durability.
Squats
Excellent for developing overall lower-body strength.
Don’t obsess over max numbers.
Focus on athletic performance.
Deadlifts
Build posterior chain strength and resilience.
Rucking
One of the most overlooked preparation tools.
Builds strength and endurance simultaneously.
Farmer Carries
Great for grip, traps, and total-body work capacity.
What About Log PT?
Everyone worries about Log PT.
The truth is that most athletes don’t need a 500-pound deadlift to survive Log PT.
They need:
- Strong shoulders
- Strong upper back
- Strong core
- Strong legs
- Mental toughness
A 25-50 pound sandbag can mimic many of the movement patterns used during Log PT.
Strength Standards That Make Sense
These are practical goals, not official standards.
Minimum
- 10 Pull-Ups
- 50 Push-Ups
- Bodyweight Squat x 20
- 5-Mile Ruck
Competitive
- 15-20 Pull-Ups
- 80-100 Push-Ups
- 80-100 Sit-Ups
- 1.5x Bodyweight Squat
- Strong sandbag carry ability
Excellent
- 20+ Pull-Ups
- Sub-9 minute PST run
- Strong swim times
- 2x Bodyweight Squat
- Excellent work capacity
Notice something?
No bench press requirement.
No bodybuilding requirement.
The emphasis remains on overall athleticism.
Sample Strength-Endurance Workout
5 Rounds:
- 10 Pull-Ups
- 20 Push-Ups
- 30 Air Squats
- 200 Meter Run
Rest 1 minute.
Then:
- 1 Mile Sandbag Carry or Ruck
Simple.
Effective.
Brutal.
Sample BUD/S Preparation Workout
For Time:
- 1 Mile Run
- 100 Push-Ups
- 100 Sit-Ups
- 25 Pull-Ups
- 1 Mile Run
Scale as needed.
This develops the blend of strength and endurance you’ll actually use.
The Real Secret
The debate between strength and endurance misses the point.
BUD/S punishes weaknesses.
If you’re strong but can’t run, you’ll suffer.
If you can run but can’t carry weight, you’ll suffer.
If you can do both but lack mental toughness, you’ll still suffer.
The ideal candidate is not a powerlifter.
The ideal candidate is not a marathon runner.
The ideal candidate is a durable, resilient, well-rounded athlete who can perform all day and come back tomorrow ready for more. Community discussions among successful candidates often repeat the same advice: be above average at everything rather than exceptional in one area and weak in another.
Final Thoughts
Do you need strength in BUD/S?
Absolutely.
But don’t make the mistake of believing strength alone will carry you through training.
Build strength.
Build endurance.
Build work capacity.
Build resilience.
Build mental toughness.
Most importantly, become difficult to break.
That’s what BUD/S is really testing.
