An exercise like the TRX or ring row is far more scalable than the pull-up. Sure, with the pull-up we can use bands, isometrics, and eccentrics, but can we do these things well?

What we see in our facility are people overusing their upper traps and biceps in vertical pulling exercises like chin-ups and pull-ups. Yet I don't see this nearly as much in the TRX row or in rows with rings.

In the ring row, I see a fully scalable exercise that I can progress or regress to my needs, something far more difficult to do well with a pull-up or chin-up.
