Stop Doing These! Bad Exercises for Shoulder Pain and Tendonitis

The shoulder is the most mobile joint in the human body — and that same freedom of movement is exactly what makes it so vulnerable when you load it incorrectly. After years of coaching movement, I’ve assessed hundreds of people with shoulder pain, and the majority of them were making things worse with exercises their bodies simply weren’t ready for. Not all exercise pain is created equal, and the glenohumeral joint is especially unforgiving when you push through the wrong kind of discomfort. Sharp, pinching, or radiating shoulder pain during a lift is your body’s alarm signal — and continuing through it is how minor impingement becomes chronic tendonitis or a rotator cuff tear. In this guide, I’ll walk you through the specific exercises that consistently cause problems for the people I train with, explain the biomechanical reasons why, and show you the safer alternatives I program in their place.

The Resistance Band That Finally Let Me Train Around Shoulder Pain

When your shoulder is angry, heavy dumbbells and barbells become your enemies — but stopping training altogether isn’t the answer either. The key is controlled, low-load tension that keeps the rotator cuff working without triggering inflammation, and that’s exactly where light resistance bands become indispensable.

What works

• Variable resistance curve means the band gets harder as you stretch it, forcing deeper rotator cuff activation in the ranges where you actually need stability instead of near-lockout where pain flares.
• Light enough that you can hit high reps (15–20+) without joint stress, but with enough tension to trigger adaptation — I’ve used these with people who couldn’t tolerate anything heavier for weeks.
• Color-coded resistance levels mean you’re not guessing intensity or progressing too fast like you might with dumbbells, which is how most people re-injure themselves.

What doesn’t

• Resistance doesn’t feel “real” to lifters coming off heavy pressing — there’s no ego in band work, and people often skip sessions because it feels too easy until pain reminds them why they’re doing it.
• Bands degrade over time with UV exposure and repeated stretching, especially if you’re doing daily rotator cuff work, so you’ll need to replace them every 12–18 months of heavy use.

I almost ditched bands entirely after a friend complained they were “too wimpy” — until his shoulder pain disappeared in three weeks and he realized that was the whole point. If you’re dealing with shoulder tendonitis or impingement, grab a set of THERABAND Resistance Bands Set and commit to the boring stuff for 4–6 weeks.

Frequently Asked Questions

What type of shoulder pain means I should stop exercising immediately?

Sharp, pinching, or radiating shoulder pain during a lift is your body’s alarm signal. Continuing through it is how minor impingement becomes chronic tendonitis or a rotator cuff tear. See a medical professional if you experience these symptoms.

Can I train shoulders with tendonitis or is rest required?

You don’t need to stop training altogether, but heavy dumbbells and barbells become counterproductive. The key is controlled, low-load tension using light resistance bands that keep the rotator cuff working without triggering inflammation.

How many reps should I do with resistance bands for shoulder pain?

Light resistance bands let you hit high reps of 15–20+ without joint stress while maintaining enough tension to trigger adaptation. This high-rep approach works because it’s light enough to avoid aggravating tendonitis.

How long does shoulder recovery take with resistance band training?

Commit to resistance band work for 4–6 weeks. The variable resistance curve forces deeper rotator cuff activation in ranges where you actually need stability instead of near-lockout where pain flares.
