What happened to your hamstring?
Your hamstring is three muscles running down the back of your thigh, and a strain is what happens when one of them gets stretched past what it can take and the fibres tear. It usually goes during sprinting, kicking, or a sudden change of pace, which is most of what rugby asks of you.
Which grade is yours?
A physiotherapist or doctor grades the injury by examining you. Roughly, this is what each grade looks like:
| Grade | Typical presentation | Can you walk? |
|---|---|---|
| Grade 1 (mild) | Tightness or dull ache during/after activity | Yes, with some discomfort |
| Grade 2 (moderate) | Sharp pain during sprinting, noticeable weakness | Yes, but limping is common |
| Grade 3 (severe) | Sudden pop, immediate intense pain, possible bruising | Difficult without assistance |
1–3 weeks
Grade 1 return
Most common grade
4–8 weeks
Grade 2 return
Needs structured rehab
3–6 months
Grade 3 return
May need surgery
Recovery timeline
Protect it and let the swelling settle
Days 1–3
Follow PEACE principles: Protect from further damage, Elevate the leg, Avoid anti-inflammatory medications in the first 48 hours (they can slow healing), Compress with a bandage, and Educate yourself on expected recovery. Your physio may recommend ice for 15–20 minutes at a time in the acute phase.
Gentle loading starts
Days 4–14
Begin pain-free range of motion exercises. Isometric holds (pressing your heel into the ground without movement) rebuild tendon tolerance. Walking should be comfortable before progressing.
Build the capacity back
Weeks 2–4
Progress to eccentric loading, which is where the Nordic hamstring curl earns its reputation. Your physio will typically take you through assisted eccentric work and build towards full range. Add single-leg Romanian deadlifts and hip bridges.
Return to running
Weeks 3–6
A typical graduated running programme progresses from low-intensity jogging through increasing speeds over multiple sessions, guided by your physiotherapist. Add change-of-direction work only after pain-free sprinting.
Return to contact
Weeks 4–8
Full-speed rugby-specific drills with contact pads. Complete at least two full training sessions before match play. Your physio should clear you based on strength testing, not just pain levels.
The Nordic hamstring curl: your insurance policy
Kneel on the ground with your ankles held down, then lower your body forward slowly, using only your hamstrings to control the descent. It does not take much volume to be worth doing. Two or three sets twice a week is a normal place to start, and your S&C coach can adjust it once the movement feels controlled.
When to worry
- Bruising spreading down your thigh within 24 hours, which can mean a higher-grade tear
- No improvement in pain after 5–7 days of rest
- Pain that wakes you at night
- A visible dent or gap in the muscle belly
- Weakness that is not improving with rehab, in which case ask your doctor about imaging
