Exercise guidance based on established strength-training principles and practical programming.
Internal rotation targets the subscapularis, the rotator cuff muscle on the front of your shoulder blade. Balancing internal rotation work with external rotation training ensures complete rotator cuff development and shoulder health.
When to use it
Use for complete rotator cuff training.
Who it's for
All levels working on shoulder health.
Lie on your side with the working arm on the bottom, elbow bent at 90 degrees. Rotate your forearm down toward your stomach while keeping your elbow stationary. Use very light weight.

We slot it into the right day with sets, reps, and progression you can follow.
Lie on side with working arm on bottom.
Bend elbow to 90 degrees, forearm pointing up.
Hold light dumbbell in hand.
Rotate forearm down toward stomach.
Return slowly to starting position.
Complete reps then switch sides.
Targets subscapularis muscle.
Use very light weight.
Balance with external rotation work.
Use internal rotation to balance external rotation work and complete rotator cuff training. Program 3 sets of 15-20 reps per arm, typically doing slightly fewer sets than external rotation since the subscapularis is often already dominant.
Using too much weight.
Loading more weight than you can control on the Internal Rotation often creates compensations that shift work away from your Subscapularis. Reduce the load until each rep follows the intended path.
Moving too quickly which reduces time under tension.
Rotational exercises like the Internal Rotation generate force through your midsection. This mistake reduces control and can shift work away from your Subscapularis. Move deliberately through the intended range.
Not full range of motion.
Cutting the range of motion short on the Internal Rotation can reduce the training stimulus for your Subscapularis. Use the largest comfortable range you can control without changing the intended setup.
All levels working on shoulder health.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 15-20 reps per arm. Rest 30 seconds.
