How to perform Lower Back-SMR
- In a seated position, place a foam roll under your lower back. Cross your arms in front of you and protract your shoulders. This will be your starting position.
- Raise your hips off of the floor and lean back, keeping your weight on your lower back. Now shift your weight slightly to one side, keeping your weight off of the spine and on the muscles to the side of it. Roll over your lower back, holding points of tension for 10-30 seconds. Repeat on the other side.
Muscles worked
- Core (primary): braces the trunk and resists twisting to protect the spine.
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
- Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
- 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
- Cranking with the hip flexors or neck instead of moving from the trunk.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Bouncing into the stretch instead of holding it steadily.
