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.
I'm going to describe a little 6-week program that I call Tsunami Training (I'll get to why I call it that a little later). It's based, for the most part, on training methodologies that I picked up from Ian King and Charles Poliquin, with some razzle-dazzle thrown in by myself.
The strength and conditioning field is like no other. Coaches have bitter enemies and die-hard devotees – and sometimes a person will qualify as both depending on the day of the week. There are insane egos and there are humble, incredibly bright coaches who go unnoticed. Finally, there are a lot of coaches who people really don't get.
