If you want the most effective hamstring exercises, the short answer is that strength beats stretching, especially for runners. The exercises that protect your hamstrings load them through their full range and train them to resist lengthening, the exact thing that fails when a hamstring strains. Build that strength and you run faster, recover better, and tear less.
Here is where to start today:
- Train hamstrings two to three times a week, not just on leg day
- Lead with eccentric work like Nordic curls and slow Romanian deadlifts
- Add a hip-hinge pattern and a knee-bending curl to cover both jobs the hamstring does
- Progress load and range gradually rather than chasing soreness
- If you have sharp or lingering hamstring pain, get it assessed before loading hard
Below, a Fort Collins physical therapist breaks down the best hamstring exercises, how to program them, and the mistakes that keep runners stuck.
Why Hamstring Strength Matters So Much for Runners
Your hamstrings do two jobs at once: they extend your hip to drive you forward and they control your knee as your leg swings through. During running, they work hardest as they lengthen under load, decelerating your shin right before your foot lands. That high-speed, lengthening contraction is exactly where strains happen.
Strong, resilient hamstrings absorb that load instead of failing under it. They also help your glutes power your stride, take strain off your knees, and keep your pelvis stable mile after mile. Stretching alone does not build any of that, which is why a runner who only stretches keeps tweaking the same hamstring.

The Best Hamstring Exercises
These cover both hamstring jobs, hip extension and knee control, and they progress from foundational to advanced. Start with what you can do with clean form, then build.
- Romanian deadlift (RDL): the foundation. Hinge at the hips with a soft knee, lower the weight along your legs with a flat back, and feel the hamstrings lengthen, then drive your hips forward to stand. Trains hip extension under load.
- Nordic hamstring curl: the gold standard for injury prevention. Kneel with your ankles anchored and lower your torso toward the floor as slowly as you can control, then push back up. Research links this eccentric exercise to large drops in hamstring strains.
- Single-leg RDL: builds the balance and control running actually demands, and exposes side-to-side weakness most runners do not know they have.
- Hamstring bridge and curl: heels on the floor or a ball, lift your hips and curl your heels toward you to train the knee-bending role of the hamstring.
- Hip thrust: loads hip extension hard with the glutes and hamstrings working together, which transfers directly to stride power.
Quality beats weight here. A controlled Nordic or RDL through full range does far more than heavy, sloppy reps.
How to Program Hamstring Work as a Runner
Strength only protects you if you do it consistently. Aim for two to three sessions a week, with at least a day between hard hamstring days and hard runs or speed work.
- Start with two exercises: one hip-hinge (RDL) and one eccentric or curl (Nordic or bridge curl)
- Use 2 to 4 sets of 6 to 12 reps, slow on the lowering phase
- Add load or range every week or two as it feels easy and pain-free
- Keep heavy hamstring lifting away from your hardest running days
For runners, this strength work pairs best with smart training load. Building it alongside your strength training for runners is what turns short-term relief into long-term durability.
Common Hamstring Mistakes Runners Make
Most hamstring trouble comes down to a few avoidable patterns.
- Only stretching: a tight-feeling hamstring is often a weak or overworked one. Stretching it can feel good but does not build capacity.
- Skipping eccentric work: the lengthening contraction is where strains happen, so it is the contraction you most need to train.
- Going too heavy too soon: piling on load before your form and range are solid is a fast track to a flare.
- Ignoring side-to-side differences: running is single-leg, so a strong left and a weak right still leaves you exposed.
Strain vs Tendinopathy: Know What You Are Dealing With
Not all hamstring pain is the same. A strain is an acute injury, often a sharp pull mid-stride with tenderness in the muscle belly. High hamstring tendinopathy is more of a deep, nagging ache right under the sit bone that worsens with sitting, sprinting, or hill running.
Both respond to progressive loading, but the starting point and pace differ. Pushing a tendinopathy like a fresh strain, or stretching an irritated high hamstring tendon aggressively, usually backfires. This is where an assessment saves you weeks.
When to See a Physical Therapist
You can build hamstring strength on your own, but some signs mean it is worth getting eyes on it first. See a PT if you felt a sharp pull or pop, if pain lingers more than two to three weeks, if it keeps returning every time you ramp up mileage, or if deep sit-bone pain flares with sitting and speed work.
At Up and Running Physical Therapy in Fort Collins, every session is one-on-one with a Doctor of Physical Therapy. We use our 3-Step Recovery Method to find the real cause, calm the irritation, and rebuild hamstring strength so you get back to training without pills, surgery, or endless rest.
Frequently Asked Questions
What is the best hamstring exercise for runners?
The Nordic hamstring curl is the most proven for preventing strains because it trains the eccentric, lengthening contraction where injuries happen. Pair it with Romanian deadlifts for hip extension strength, and you cover both jobs the hamstring does while running.
Should I stretch or strengthen a tight hamstring?
For most runners, strengthening helps more than stretching. A hamstring that feels tight is often weak or overworked, and building strength through full range usually relieves that tension better and longer than stretching alone.
How often should runners train hamstrings?
Two to three times a week is plenty, with a day between hard hamstring sessions and hard running or speed work. Consistency over weeks matters far more than occasional heavy sessions.
How do I know if I strained my hamstring or have tendinopathy?
A strain usually feels like a sharp pull mid-stride with tenderness in the muscle belly, while high hamstring tendinopathy is a deep ache under the sit bone that worsens with sitting and sprinting. They are loaded differently, so an assessment helps you start in the right place.
Can hamstring exercises make me a faster runner?
Yes. Stronger hamstrings extend the hip more powerfully and control the leg better at speed, which improves stride power and efficiency while lowering injury risk. Strength training is one of the most reliable ways for runners to get faster and stay healthy.
How long until hamstring strengthening helps?
Many runners feel more stable within a few weeks of consistent work, while building true strength and resilience takes a couple of months. The runners who see lasting results treat it as ongoing training, not a short-term fix.
Build Hamstrings That Keep Up With Your Goals
Strong hamstrings are some of the best insurance a runner can have. At Up and Running Physical Therapy in Fort Collins, we help runners and active adults build the strength to run faster and stay healthy, with one-on-one care and no pills, surgery, or rest required.
