This program may fit
Sudden, localized posterior-thigh pain while sprinting, accelerating, kicking, jumping, or being forced into hip flexion with the knee extended, with pain during resisted knee flexion, hip extension, or gentle hamstring lengthening and temporary loss of running or sport function.
Get assessed first
A loud pop with immediate disabling buttock or thigh pain; extensive or rapidly spreading bruising; marked weakness, buckling, a palpable defect, or inability to walk; pain centered at the sit bone with sciatic-type symptoms; an adolescent with focal sit-bone pain after sprinting, kicking, or forced stretching; gradual deep-buttock pain worsened by sitting; back pain or radiating symptoms below the knee; direct-impact injury; recurrent strain; anticoagulant use; or failure to improve.
Stop signs
Call 911 for chest pain, trouble breathing, coughing blood, fainting, or a newly cold, pale, or numb leg. Seek emergency assessment for rapidly escalating thigh pain with tense swelling, numbness, or weakness. Seek same-day sports medicine or orthopedic assessment for a pop followed by inability to walk or use the leg, major weakness or buckling, a palpable gap, extensive rapidly increasing bruising or swelling, proximal buttock pain with sciatic symptoms, or focal sit-bone pain in an adolescent. New one-sided calf or whole-leg swelling, warmth, or redness also requires urgent assessment.
Check the next morning
A home program should be conservative. Familiar discomfort up to about 3 out of 10 can be acceptable during strength work when there is no sharp or tearing sensation, limp, or compensation and symptoms return to baseline by the next morning. This is a practical rule, not a validated universal threshold. Sprinting should be pain-free.
Fit and safety
Confirm this is the right diagnosis.
This program is intended for athletes who have already been evaluated and told a grade I or II hamstring muscle or myotendinous strain is the likely diagnosis. It is not a self-diagnosis tool and does not cover proximal hamstring tendinopathy, a tendon avulsion, a complete tear, or postoperative rehabilitation.

Do not self-start with these warning signs
Call 911 for chest pain, trouble breathing, coughing blood, fainting, or a newly cold, pale, or numb leg.

Seek same-day sports medicine or orthopedic assessment for a pop followed by inability to walk or use the leg, major weakness or buckling, a palpable gap, extensive rapidly increasing bruising or swelling, proximal buttock pain with sciatic symptoms, or focal sit-bone pain in an adolescent. New one-sided calf or whole-leg swelling, warmth, or redness also requires urgent assessment.
This is a diagnosis-specific home program, not a substitute for an examination. A clinician may change the exercise, dose, range, or timeline based on your history.
Your home program
Restore strength through range, then rebuild speed and sport workload.
The exact sequence and dose should be individualized. Start with controlled contractions and normal walking, then progress resistance and range before high-speed work. Mild discomfort may be acceptable during selected strength exercises, but sprinting and return-to-sport testing should be pain-free.
- Frequency
- Strength 2 to 3 nonconsecutive days per week; low-load isometrics may be used daily early; running on nonconsecutive days initially
- Equipment
- Mat, stable chair or counter, smooth floor with sliders or towels, optional backpack or weights, safe flat running area
- First checkpoint
- Review walking and loading at 1 to 2 weeks; reassess before running above 80 percent effort
- Primary goal
- Pain-free maximal running and sport-specific workload with restored longer-length strength
-
Exercise 1Daily early if useful
Heel-dig isometric
Dose3 sets of 6 to 10 repetitions with a 5-second hold
Lie with both knees bent. Press the injured heel down and slightly toward the body without letting it slide. Begin around 30 to 50 percent effort.
Make it easierUse both heels, place the heel closer to the hips, or reduce effort.
Progress itMove the heel farther away, increase effort, then use the injured leg alone at several knee angles.
My starting dose or notes
-
Exercise 22 to 3 days per week
Short- to long-lever bridge
Dose2 to 3 sets of 6 to 12 repetitions
Press through both heels, lift the hips without forcing the back, pause briefly, and lower slowly.
Make it easierUse a smaller lift, place the heels closer to the hips, or use an isometric hold.
Progress itMove the heels farther away, use a staggered stance, then progress to a controlled single-leg bridge.
My starting dose or notes
-
Exercise 32 to 3 days per week
Eccentric slider curl
Dose2 to 3 sets of 6 to 12 repetitions with a 3- to 4-second lowering phase
Bridge on both legs with the heels on sliders or towels. Slowly slide the heels away, lower the hips, reset the heels, and repeat.
Make it easierUse a shorter slide or move one heel at a time.
Progress itKeep the hips up through a full bilateral curl, then use a single-leg lowering phase. An assisted Nordic is a later alternative only with a secure setup.
My starting dose or notes
-
Exercise 42 to 3 days per week
Supported hip hinge or kickstand Romanian deadlift
Dose2 to 3 sets of 6 to 10 repetitions per side
Hold a counter, keep a soft knee, push the hips backward, and stop before pain or loss of pelvic control.
Make it easierUse both legs, a smaller range, and no external load.
Progress itIncrease range, add a backpack or dumbbell, then use a kickstand or single-leg position.
My starting dose or notes
-
Exercise 52 to 3 days per week
Side plank with controlled trunk work
Dose2 to 3 holds of 15 to 30 seconds per side
Keep the ribs and pelvis stacked without rotating or sagging. The goal is controlled trunk and pelvic endurance, not maximal fatigue.
Make it easierBend the knees and support from the forearm and lower knee.
Progress itUse straight legs, extend the hold, or add 6 to 10 slow trunk rotations.
My starting dose or notes
-
Exercise 6Nonconsecutive days initially
Graded running exposure
DoseExample starting exposure: 2 to 3 sets of 4 controlled 30-meter runs with full walking recovery
After walking and easy jogging are pain-free and basic strength is controlled, begin near 50 to 60 percent of perceived maximum speed. Treat each run as rehabilitation rather than a test.
Make it easierUse walk-jog intervals or shorter strides at a lower speed.
Progress itIncrease either speed or total running volume at a later session, not both. Use smaller increases as speed approaches maximum and retain full recovery.

Video examples are options, not additions. Links or promotions inside the video are provided by E3 Rehab and are not part of this program. This program is only for an already-evaluated, uncomplicated grade I or II muscle or myotendinous strain. It does not cover a complete tear, tendon avulsion, proximal hamstring tendinopathy, an adolescent apophyseal avulsion, or postoperative rehabilitation. Sprinting and high-speed sport work should be pain-free.
Read the sports injury evaluation guideSymptom response
Let the next day guide the dose.
A home program should be conservative. Familiar discomfort up to about 3 out of 10 can be acceptable during strength work when there is no sharp or tearing sensation, limp, or compensation and symptoms return to baseline by the next morning. This is a practical rule, not a validated universal threshold. Sprinting should be pain-free.
Green light
Discomfort stays near 0 to 3 out of 10 during strength work, movement remains normal, and symptoms are no worse later that day or the next morning.
Yellow light
Pain rises across repetitions, exceeds 3 out of 10, alters movement, or remains meaningfully worse the next morning. Reduce range, load, repetitions, or running speed or volume and repeat the prior successful level after symptoms settle.
Red light
Stop for a new pop or tearing sensation, rapidly increasing bruising or swelling, a palpable defect, marked weakness, buckling, inability to walk, or new neurologic symptoms. Stop sprinting with any hamstring pain and reassess before returning to high-speed progression.
Change one variable at a time
When symptoms are too reactive, first reduce range, resistance, repetitions, or frequency. When the current dose feels controlled for several sessions, progress only one of those variables.
Progression
Build capacity in stages.
-
Stage 1: restore comfortable movement and activation
Normalize walking and use heel digs, bilateral bridge, low-load trunk work, and tolerable cycling or other conditioning.
-
Stage 2: build range and strength
Add sliders and hip hinges. Increase range, repetitions, and then resistance while monitoring the next-day response.
-
Stage 3: restore speed and eccentric capacity
Advance to unilateral and longer-length work, pain-free running above 70 to 80 percent, acceleration, and later change of direction.
-
Stage 4: rebuild sport workload
Reach pain-free maximal speed, repeated sprint or endurance demands, sport-specific skills, and unrestricted training before competition.
Signs you are ready for the next stage
- Walking and daily function are normal without a limp.
- There is no meaningful pain with palpation, resisted contraction, or longer-length loading.
- Strength and active range are approaching baseline and the demands of the sport.
- Maximal sprinting, acceleration, deceleration, and required direction changes are pain-free.
- High-speed volume and intensity approximate usual training or competition demands.
- A full unrestricted practice is completed without symptoms during or over the following 24 hours, and the athlete feels confident.
When to schedule an evaluation
Review gait, bruising, range, and exercise response after 7 to 14 days. Obtain formal review before exceeding about 70 to 80 percent running speed when testing is unavailable, if there is no clear week-to-week improvement after two to three weeks, if running cannot be progressed by about four to six weeks, or if setbacks recur. Competitive sprinters and field-sport athletes should have clinician-supervised return-to-sport testing; no single home test clears competition.

Common questions
Questions about this program
Should I rest until there is no pain?
No. Temporarily remove sprinting, forceful stretching, and other provocative loads, but begin controlled movement and progressive strengthening once the diagnosis is established and the load is tolerated.
Should I stretch the hamstring right away?
Avoid forceful end-range stretching early. Gentle active range is reasonable, and later strength through increasing muscle length restores usable range. Stretching alone is not an adequate rehabilitation program.
Can rehabilitation exercises hurt?
Mild discomfort can be acceptable. A small trial of 43 men allowed pain up to 4 out of 10 and found similar return-to-play times; it was not large enough to establish reinjury safety. This home plan uses a more conservative 3 out of 10 rule and requires symptoms to return to baseline by the next morning. Sprinting should be pain-free.
Do I need an MRI?
Usually not for a clinically diagnosed grade I or II strain. MRI or ultrasound is useful when a complete tear, tendon avulsion, atypical diagnosis, or unexpectedly poor course is suspected. Imaging does not independently determine readiness.
Are Nordic exercises required?
No. They are a useful later eccentric option and have prevention evidence, but they are not an appropriate first exercise. Full-range slider and hinge progressions can build capacity, and a Nordic requires a secure setup.
When can I compete again?
Not when everyday pain first disappears. Return after pain-free maximal speed, required sport actions and volume, restored strength and range, confidence, and tolerance of unrestricted practice.
