How to perform Arm Circles
- Stand up and extend your arms straight out by the sides. The arms should be parallel to the floor and perpendicular (90-degree angle) to your torso. This will be your starting position.
- Slowly start to make circles of about 1 foot in diameter with each outstretched arm. Breathe normally as you perform the movement.
- Continue the circular motion of the outstretched arms for about ten seconds. Then reverse the movement, going the opposite direction.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
- Back (secondary): pulls the arms down and toward the torso and keeps the spine stable.
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
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- 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.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Bouncing into the stretch instead of holding it steadily.
