The best strength exercises for runners, cyclists, and triathletes
Most endurance athletes know they should strength train.
But then the questions start:
What exercises actually matter?
How heavy should I go?
Will this make me sore and ruin my training?
The truth is: the best strength training for endurance athletes is simple, targeted, and focused on making you more durable instead of exhausted.
As both an endurance athlete and coach, one of the biggest lessons I’ve learned is this:
good strength training should support your specific sport.
Running, cycling, and triathlon all place repetitive stress on the body.
That means you need strength work that improves:
force production
joint stability
tendon resilience
posture under fatigue
injury resistance
The goal isn't bodybuilding or looking aesthetically.
The goal is:
staying healthy,
improving economy,
tolerating more training.
A broad review found that properly designed strength training improves endurance performance, movement economy, and fatigue resistance in endurance athletes.
Every athlete should focus on:
Glutes → hip power + pelvic stability
Hamstrings → posterior chain + injury prevention
Quads → force + support
Calves / feet → stiffness + elastic return
Core → posture + force transfer
Upper body (especially swimmers / triathletes) → posture + efficiency
1. Split Squats / Bulgarian Split Squats
Why:
One of the best exercises for:
single-leg strength,
hip stability,
balance,
running mechanics.
Benefits:
mimics running demands,
improves pelvic control,
reduces asymmetries.
How:
3–4 sets of 6–10 reps each side
2. Romanian Deadlifts (RDLs)
Why:
Builds:
hamstrings,
glutes,
posterior chain.
This is huge for:
run propulsion,
bike power,
injury prevention.
Benefits:
improves hip hinge,
improves force production,
protects hamstrings.
How:
3–4 sets of 5–8 reps
3. Step-Ups
Why:
Very sport-specific.
Great for:
single-leg force,
knee drive,
coordination.
Benefits:
improves uphill strength,
race durability.
How:
controlled box height,
3 sets of 6–10 reps
4. Calf Raises (Straight + Bent Knee)
This is massively overlooked.
Why:
Calves are essential for:
run stiffness,
energy return,
tendon resilience.
Benefits:
reduce Achilles issues,
improve run economy.
How:
straight leg = gastrocnemius
bent knee = soleus
Do:
3–4 sets of 12–20
Research increasingly highlights calf and lower-leg capacity as key for runners’ resilience and efficiency.
5. Single-Leg RDLs
Why:
Great for:
balance,
foot control,
posterior chain.
Benefits:
improves stability,
challenges coordination.
How:
2–3 sets of 6–10 each side
6. Core Anti-Rotation Work
Examples:
Pallof press
dead bugs
side planks
bird dogs
Why:
Core for endurance is:
posture,
control,
force transfer.
Not six-pack workouts.
Benefits:
better run form,
stronger bike position,
less fatigue collapse.
7. Pulling Exercises (Rows / Pull-ups)
Especially useful for:
triathletes,
swimmers,
cyclists in aero.
Why:
Helps:
shoulder health,
posture,
swim mechanics.
Good options:
chest-supported rows
lat pulldowns
pull-ups
8. Hip Stability / Glute Med Work
Examples:
lateral band walks
side lying abductions
Copenhagen plank variations
Why:
Supports:
knee tracking,
pelvic stability,
injury prevention.
This is especially useful for runners.
In general:
1–3 sessions/week
Off-season / base:
heavier work
more progression
Race build:
maintain strength
lower volume
Taper:
reduce significantly
Good weekly structure:
Option 1 (2 sessions):
Session A: lower body strength + core
Session B: full body + stability
Option 2 (1 session):
full body essentials
Doing random gym exercises
Machines and fluff won’t help much.
Chasing soreness
Soreness ≠ progress.
Bad timing
Heavy leg day before:
long run,
intervals,
race day
…is asking for trouble.
Skipping progression
Strength still needs:
overload,
intent,
consistency.
As an endurance athlete, some of the biggest improvements I’ve made came from getting stronger in the basics:
better single-leg control,
stronger posterior chain,
better calf capacity.
That helped me:
tolerate more volume,
stay healthier,
and feel stronger late in races.
And as an endurance athlete that's all that matters.
The best strength exercises for endurance athletes are not the fanciest ones.
They’re the ones that:
make you more durable,
improve efficiency,
support consistent training.
Keep it simple:
get stronger,
move well,
recover properly.
Because the best endurance athletes don’t just train hard.
They build bodies that can keep doing it.

Because better performance starts with a stronger foundation.
