Bigger Arms and Better Recovery with THIS

Get Massive, Muscular Arms by improving recovery and predicting your training plateaus!

Traditional training uses generalized templates to prescribe your exercise. They have their uses, but I'll show you A BETTER WAY.

Customize your training TO YOU, by using personalized Key Performance Indicators (KPIs) to:
-increase body awareness
-optimize recovery-adaptation
-build more muscle

This powerful UPGRADE is a small sample of what to expect in the highly anticipated book 'Massive, Muscular Arms'.
✅ BONUS: in Chapter 8 I show you how to use my NASA research to improve your own recovery.

After 30 years in the making, David 'Arm' Barr joined with the world's leading fitness publisher, Human Kinetics, to feature more than 75 exercises and hundreds of coaching and execution tips to make bigger arms your reality.

FAQ: Why have you been described as the Elon Musk of fitness?


It wasn’t an entirely flattering comparison, but like Elon Musk, in addition to the NASA-space connection, I have Asperger’s syndrome and the ‘unusual’ sense of humor that comes with it. Also like Elon, our results are achieved by applying the 2 benefits of Asperger’s:

-we think differently about solving problems*

-we do so obsessively

The result is a Massive upgrade to existing methods, along with new innovations to make your gains come faster.

*I even kick off Chapter 1 by quickly showing you the power that comes from reverse engineering a problem (aka Musk’s 'First Principles' approach), which you then get to apply using the rest of the book.

FAQ: Are your arms really as big as they seem in the banner?

Absolutely not. I was playing with poses during a workout and stumbled on the old childhood trick of pushing my arm against my knee. I’m still a meathead at heart and liked the way it looked.

As a bonus, it helps me to take a shot at the standard BS hyperbole of the industry, which is the antithesis of my mission. Don't miss the REAL pic at

Until next time, Raise The Barr
