Josh Smith packed on a whopping 70lbs and added 3 Inches to his arms! Yes THT training is POWERFUL!

Myra Marshall knows how to train

Myra said, “I searched through tons of websites, blogs, and forums and then I found MuscleHack and started reading every article I could get my hands on. The human body is the human body, male or female; we are just as capable of doing the same exercises as men and we should do the same exercises that they do.”  ~ Myra Marshall.

Serge Ouellette couldn't believe his fast gains

Serge said, "“I was actually blown away how much my body has changed after completing week 6. I’m on week 7 of THT and I am VERY satisfied. Both pictures were taken in the morning, cold, no pump or anything. Looking forward to many weeks, make that years of THT. Loving every minute of your programs and guidance. Life changing. Thanks!”

Eric Leroyer gains muscle & loses fat

“Eric said, "Just finished 10 weeks of THT. Great results. I weighed 63kg at 15% Body Fat before. I weighed 69Kg at 12.5% after. Huge difference!”  (Note: that’s a 13.2lb increase in body weight with a 2.5% drop in body fat at the same time!)

Cody Volckmar gains 19lbs & 2inches on his arms

Cody said, "Stumbling upon your program one day on Google changed my life. I have always had a very skinny body. Your methods and techniques have literally cut out the BS in the training game. Using THT I have gained 5cm on my biceps (about 2 inches). Starting weight 71kg. Peaked at 80kg. 8kg = a gain of ~19lbs."

Mark House completely transforms at 45

Mark said, “At 45 years old and 297 pounds, I decided it was time to transform. I downloaded your THT workout program to learn as much as I could. Thank You for your free programs and for keeping it REAL!!”

2 U.S. Soldiers Get Jacked on THT!

They said, "I have worked out for the last 7 years, but I have never seen results like this.The results were amazing; we both put on about 5 pounds of muscle in 6 weeks, and did not see any fat gain as you promised. You definitely have something going. In just 2 months, our bodies were totally transformed.”

The Best Exercises

THT uses the most effective growth stimulating exercises as identified by electromyography tests (THT).


How often to work each muscle

THT tells you when and how often to train each muscle meaning you strike the right balance between over-training and under-training.


Sets & Reps

THT tells you exactly how many sets and reps to do for every muscle. There is an optimal number for maximum growth stimulation.


3-day and 5-day routines

There are 3-day and 5-day/wk routines. Use the one that fits your lifestyle or cycle both routines for 10 weeks each.

What MuscleHack Readers Are Saying

Don’t just take it from me, let other readers tell you what happened their bodies on THT!

“I found the MuscleHack site in January of this year. I couldn’t believe the difference it made in my training! I gained more muscle and got so much stronger in 2 months than I had the entire YEAR of training before! The difference in the amount of muscle I have now is amazing!”

Brandi McAtee - NPC Competitor (Yes THT is for women too)

“Let me put this straight: THT is the BEST program out there. I’ve never had these kind of results from any other workout. I’ll never train another way again”

Eddie Mathewson

“I saw a book called Targeted Hypertrophy Training. I clicked it, read it, and realized I had been training the wrong way for 20 years! THT has brought to me the knowledge and understanding of how to actually build muscle the correct way.” 

Sean Alexander Brown
