Here’s a quote from former pro bodybuilder Lee Labrada on the training growth threshold:
The growth threshold is the point at which the level of fatigue in the muscle is high enough that a growth response is elicited. Your goal during a workout should be to fatigue the target muscles more and more with each succeeding set. In other words, you want the muscles to progressively get more and more tired out, until you reach a point where the muscles are functionally ‘worn out.’ Signals are sent to the brain that set up the compensation, or growth, process during the post workout period, so that in future workouts you can handle it.
Hitting the Growth Threshold within a minimum number of sets is the reason the Old Man, Young Muscle workout is so effective and efficient…
You get short rests between sets coupled with slow-twitch exhaustion for faster fast-twitch activation. In other words, you reach the Growth Threshold quickly—and that means more mass fast.
GROW like never before: Get the Stretch-First POF Pre-Ex Workout as well as the Base-STX Workout, which both include the ideal exercise for each muscle and the best stretch and contracted add-on moves for mass, in Old Man, Young Muscle.
And you still get The Muscle-On, Belly-Gone “Diet” ebook FREE for a limited time when you add Old Man, Young Muscle to your mass-building library. Go HERE.
Till next time, train hard—and smart—for BIG results.

Specialize for Muscle Size
Specialization training is when you devote your time and attention to building up a particular lagging muscle group or set of muscle groups.
Most guys in the gym use specialization to build bigger “visible” muscles like arms, forearms, or calves, but little do they know that they’re wasting countless sets and reps…
Plus, they initiate no growth hormone response—meaning all their specialized sets are basically worthless!
Instead of wasting effort, you can pack on slabs of muscle mass FAST while skyrocketing your testosterone levels to pave the way for even FASTER muscle growth through Alpha-3 Specialization.A
But instant results aren’t the only perk of Alpha-3 Specialization…
