Trevor,

It’s not too bad on the 1st rep, but it does get worse as you progress.

That’s ok because we use these variations to find weak points, and we found one.

It seems you can get a little tighter at the start, and I also suggest resetting at the top between reps.

You are doing a good job making your arms long at the start, but fatigue is making the problem worse (by design).

Before we add in extra back work, try resetting your arms/back at the top of each rep before you lower it next time.

See if that works, and if it doesn’t we will go from there.

Sometimes a simple readjustment between reps is all it takes.
