I wouldn't quite say I have an injury to my rotator cuff but when I start to do a decent amount of pushups I seem to start aggrevating it.
Which is the best style of pushups to avoid this?
BTW I'm starting to do rotator cuff exercises with some resistance bands from tomorrow so that's that part out of the way.
Since there are four muscles in the rotator cuff, it's hard to say based on your question.
However, i suggest three things:
1. Warmup up well for any pressing exercise. Better then you would for other excercises.
2. pushup with your elbows in close to your body. Do not let them flare.
3. Stop doing so many pushups by adding weight or switch to bench.
