Half-Inch of Arm Mass in 1 Workout

Jonathan's arm measurement

In the last training newsletter, I mentioned how I caught a bug from my granddaughter and missed a week of workouts.

Yes, it sucked. But on the flip-side, I noticed my physique getting bigger and better over the get-well week. It reminded me of the article on adding a half-inch of arm size after only one workout. Let me explain… [Read more…]

Intensity Guru: “Pull Back for More Mass”

Pics of Ellington Darden (doing shoulder presses and on the cover of Strength & Health)

In recent newsletters I’ve laid out some new theories on training to failure—basically that it can slow hypertrophy.

Not always, but too much creates severe damage, which saps recovery and growth. Doing only one set to failure while stopping others a rep or two short appears to be a better way to stimulate massive amounts of fast-twitch growth fibers (more on that below). [Read more…]
