How to perform Runner's Stretch
- It's easiest to get into this stretch if you start standing up, put one leg behind you, and slowly lower your torso down to the floor.
- Keep the front heel on the floor (if it lifts up, scoot your other leg further back).
- Place your hands on either side of your front leg. To get more out of this stretch, push your butt up toward the ceiling, and then gradually lower it back toward the floor. You'll Stretch the hip flexor of the back leg and the hamstring and buttocks of the front.
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.
- Own the largest range you can control with clean form before you chase extra reps.
- 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.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Bouncing into the stretch instead of holding it steadily.
