Rhomboids菱形肌
Function
The diamond between the spine and the inner scapular border: retracts and elevates the shoulder blades. The postural muscle that 'opens' the shoulders — squeeze two seconds at the end of every row and you're training it.
Best Exercises & Form Cues
-
Seated Row (End-Range Squeeze)
- Equipment
- Seated row machine
- Sets & Reps
- 3-4 sets × 10-12 reps · rest 90 s
- How to do it
- Standard seated row with an end-range emphasis: when the handle reaches the abdomen, retract the shoulder blades hard and hold 2 seconds (rhomboid-led); lower to a protracted stretch.
- Common mistakes
- No pause at the finish, leaning way back, shrugging
-
Face Pull
- Equipment
- Cable station + rope
- Sets & Reps
- 3-4 sets × 15-20 reps · rest 60-90 s
- How to do it
- Pull the rope toward the forehead, finishing with hands apart at ear level and elbows out; squeeze one second in external rotation at the scapular-spread position (rear delts + cuff).
- Common mistakes
- Pulling to the chest (becomes a row), too much weight, no external-rotation finish
-
Band Scapular Retraction
- Equipment
- Band
- Sets & Reps
- 2-3 sets × 15-20 reps
- How to do it
- Arms straight ahead holding the band ends, elbows stay straight; only the shoulder blades squeeze back (the band opens with them); 2-second rhomboid squeeze at the end; slow return.
- Common mistakes
- Bending the elbows (becomes a row), shrugging, leaning back
-
Reverse Fly
- Equipment
- Dumbbells (bent-over)/reverse pec deck
- Sets & Reps
- 3-4 sets × 12-15 reps · rest 60 s
- How to do it
- Hinge to near-horizontal (or chest on pad); elbows slightly bent and fixed; open to the sides up to shoulder height, retract the scapulae at the end, lower slowly.
- Common mistakes
- Shrugging (traps take over), swinging straight arms, torso bouncing
Stretching & Recovery
- Cat arch with head turn
- Elbow-clasp forward bend
