Q: I’m making some incredible progress using your Double-X Overload technique, but I wanted to let you know that I don’t just use it on my work sets. DXO works for warmup sets, too. I usually use it on at least one of my two warmup sets for the big [midrange] exercises, and I feel much stronger on my work sets. Great technique!

A: That’s a good tip. We love feedback from fellow weight trainers who think instead of just following the pack. One reason Double-X Overload (DXO) works so well on warmup sets is because of the enhanced occlusion and nervous system activation.

For those unfamiliar with DXO, it’s an X-Rep partial in the semi-stretch position between each full rep. That provides a slightly more explosive action, which has been shown to heighten nerve force (many top-level powerlifters do light, explosive sets for that very reason—it helps them lift more weight).
