Skull Crushers

Q: The lead-off exercise for the triceps sweep workout [in the X-traordinary Arms e-book] is lying extensions, or skull crushers. You describe the best grip width and how to use an EZ-curl bar for more long-head involvement, but I don’t like dragging a bar over to a flat bench. Can I use dumbbells for lying extensions instead of a bar?

A: Magnetic resonance imaging shows that lying extensions on a flat bench with a bar (skull crushers) mostly stress the triceps’ long head, so we classify it as a sweep exercise in the X-traordinary Arms e-book. You would think using dumbbells would be the same—but that’s not the case. [Read more…]

Progressive-Shock Size-Surge Tips

Q: I’m astounded by Jonathan’s Size Surge transformation in only 10 weeks. His arms got huge, and he said his gains really took off during the second phase when he started using Positions of Flexion. I was thinking that I should do POF for arms in phase 1 too. Like for biceps, he has two sets of barbell curls and two sets of concentration curls. Wouldn’t I make better gains if I did two sets of barbell curls followed by one set of incline curls [for stretch] then one set of concentration curls? That’s the same number of sets, but now it’s full-range POF. I could do the same for triceps too.

A: That sounds like a good plan—at least until you realize one reason phase 2 in the Size Surge program works so well is because the muscles get a progressive-shock size effect when you shift to full-range training for the last four weeks. In other words, you force more growth adaptation to happen when you add stretch-position exercises like incline curls for biceps and overhead extensions for triceps at week 7… [Read more…]
