How to perform Lying Hamstring
- Lie on your back with your legs extended. Your partner should be kneeling beside you. Raise one leg up towards the ceiling and have your partner hold the ankle. Your partner can use their shoulder to brace your leg if necessary. This will be your starting position.
- With your partner holding your leg in place, attempt to flex the knee, contracting the hamstrings for 10-20 seconds.
- Then relax your leg, allowing your partner to gently push the leg towards your head. Be sure to inform your helper when the stretch is adequate to prevent injury or overstretching. Switch sides once complete.
Muscles worked
- Hamstrings (primary): bends the knee and extends the hip through hinges and pulls.
- Calves (secondary): points the foot to power push-off and steady the ankle.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
As a mobility drill, hold each position for 20–40 seconds (or move slowly for reps) rather than training it to a heavy load.
Form tips
- Lead with the hips, keep a soft knee and hold a long, flat back through the hinge.
- Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
- Ease in until you feel mild tension, never pain, and breathe out as you sink a little deeper.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Rounding the lower back to reach lower instead of hinging at the hips.
- Leaving the seat or range on a setting that forces the joint into an awkward angle.
- Bouncing into the stretch instead of holding it steadily.
