When sciatica strikes, a lot of people instinctively stop moving altogether. It's the single most frequent mistake. Complete rest delays the nerve's recovery and keeps alive the muscle spasms that squeeze it.
What actually helps is gentle, focused movement, done on a regular basis. Below are the 5 exercises physical therapy clinics rely on most because they work best.
Should any of these exercises increase the pain in your leg, stop right away. In a severe acute phase (the first 72 hours), limit yourself to exercises 1 and 2.
Exercise 1 — Piriformis stretch
This is the key one. Start with it.
How to position yourself: lie flat on your back. Rest the ankle of the painful leg across the opposite knee. Hold the back of that opposite thigh and ease it in toward your chest.
What it should feel like: a deep pull through your buttock.
How long: 30 to 45 seconds · 3 repetitions · 2 times a day.
Why it helps: it goes straight to the piriformis muscle — the leading cause of "false sciatica" and something that makes disc-related sciatica worse. Physical therapists recommend it for sciatica more than any other exercise.
Exercise 2 — Knee to chest
How to position yourself: lie flat on your back. Draw one knee in toward your chest, keeping the other leg stretched out on the floor.
How long: 30 seconds · 3 repetitions per side.
Why it helps: it lengthens the lower back and opens up room around the pinched nerve root. It's safe to start within the first few hours of a flare-up.
Exercise 3 — Lumbar extension (sphinx)
How to position yourself: lie face down. Propped on your elbows, slowly raise your chest. Your hips stay in contact with the floor.
How long: 30 to 45 seconds · 3 repetitions.
Why it helps: it eases the pressure on the back of the disc (herniated disc). Encouraging sign: if your leg pain lessens while you hold the position, continue. If it gets worse, stop.
Exercise 4 — Cat-cow mobilization
How to position yourself: get on your hands and knees, hands below your shoulders. Breathe in while slowly arching your back (cow). Breathe out while rounding it as far as you can (cat). Keep the movement slow and smooth.
How long: 10 repetitions · 2 sets.
Why it helps: it gets the lumbar spine moving and eases tension that has built up. Perfect to do right after waking, before getting out of bed.
Exercise 5 — Sciatic nerve gliding
How to position yourself: sit at the front edge of a chair, back upright. Straighten the painful leg out in front of you (foot flexed), hold it for 5 seconds, then tuck your foot back beneath the chair.
How long: 10 slow repetitions · 1 set.
Why it helps: it "flosses" the sciatic nerve along its path and loosens adhesions little by little. Add it once you reach the subacute phase (day 3–5 onward), not in the middle of a severe acute flare-up.
Pairing exercise with therapy
Exercise eases mechanical tension. To get the most out of it:
- Before your exercises — 10 minutes of 660 nm red light gets nerve and muscle tissue ready and lowers inflammation ahead of stretching
- After your exercises — heat at 113–149°F (45–65°C) helps you hold on to the relaxation you've gained and keeps soreness at bay
- How often — 2 times a day in the acute phase (only exercises 1 and 2) · 1 time a day for maintenance (all 5 exercises)
🔷 Get more out of every exercise session
✦ 660 nm red light beforehand — gets tissues ready and lowers inflammation ahead of stretching
✦ Heat from 113°F to 149°F (45–65°C) afterward — holds on to the relaxation you gained while exercising
✦ Two 6,000 rpm motors — work out deep knots that stretching by itself can't undo

How often each day should I do these exercises?
2 times a day in the acute phase (only exercises 1 and 2). 1 time a day in the chronic phase (all 5 exercises). Doing them every day matters more than how hard you push.
Can these exercises take the place of physical therapy?
No. They help you get more out of the time between appointments. A physical therapist adapts the program to your particular situation and uses manual techniques that home exercises simply can't reproduce.
Is it possible to do these exercises at work?
Exercise 1 (piriformis stretch done seated, in its chair version) and exercise 5 (nerve gliding while seated) can be done at your desk without drawing attention. The rest need floor space.
When can I expect results?
Some relief may come as early as your first few sessions. A noticeable improvement typically shows up after 1 to 2 weeks of consistent daily practice.
🔷 The 4-in-1 Therapy Belt
✦ Heat you can adjust from 113°F to 149°F (45–65°C) — encourages blood flow and loosens muscles before your day gets going
✦ 105 medical-grade LEDs at 660 nm — a wavelength that has been clinically studied in physical therapy; gets tissues ready and helps them regenerate
✦ Two 6,000 rpm massage motors — loosen the deep muscles that exercise by itself can't release
✦ Flexible neoprene that fits waists up to 51 inches — support in between exercise sessions
