How can we take the difference of post test values when the pretest values are different?

The difference is 14% of Arm only group and 21% of the Arm + leg group. So the difference is around 7% which comes around 5-6 lbs.

Ask Lyle, I’m not an expert

Wasn’t asking you. Just making a comment.

Couple of things:

1. I think the design is not good. Your neural drive is way higher after leg exercises that most exercises feel easier (potentiation & catecholamines). If you do 3 sets of leg press, leg extension and leg curls, you will be flexing your arms even if the author told them not to. They should have it the other way- arms after legs.

About potentiation…
Do we talking about Postactivation Potentiation?

Yes, Anatoly. I think gripping the bar hard when doing leg exercises can contribute to it.
