THT THT Creator Mark McManusT.H.T. is simply the BEST workout system on the planet to build muscle fast – and it’s free.

It’s NEW (only a few years old) and is quickly sweeping around the world with tens of thousands of people signed up & training.

T.H.T. is short for Targeted Hypertrophy Training. Hypertrophy simply means “muscle growth”.

Josh Before After THT Training
Josh Smith packed on a whopping 70lbs and added 3 Inches to his arms! Yes THT is POWERFUL! You can read his full story here.

You will experience UNPRECEDENTED gains in muscle size and strength. Why? Because it’s scientifically based. As such it can TRIGGER explosive new growth in muscle tissue!

Be LIGHT-YEARS ahead of 99% of the guys at the gym. Building muscle is a science…and now you can know it!

My promise is simply this: You will experience better gains than ANYTHING you’ve ever tried before in your life. And it won’t cost you a penny – not now, not ever! THT will always be free. So you’ve nothing to lose, and everything to gain!


Why is it free? Because the idea is to build a community around THT training. I want to get these valuable insights into as many hands as possible. This community is made of real people getting real results based on actual science  – that’s my goal! (You’ll note that on most testimonials, I give a link to their facebook profile to prove that it comes from a real person.)

Targeted Hypertrophy Training

THT is designed specifically to FORCE your muscles to get BIGGER; it’s that simple. Yes, muscle growth can be FORCED to occur!

If you choose to ignore the logic, science, and non-contradictory message of this way of training, you could literally waste YEARS of effort trying to build muscle with inferior, nonsensical systems.



“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 I would dare say, they are just very COMPLETE from diet to exercise. Thanks!” Serge Ouellette. His full THT testimonial here.


“I’ve gone from 175lbs to 211lbs currently. I used to do classic pyramids, ate like crap, ate 6000 calories and tried to cut after. Except…it didn’t work! Now I’m vastly stronger than I once was, I have a six-pack (and I ride a desk for 8 hours a day at work) and have more muscle mass than I’ve ever had in my entire life.” Adam Weichel (his facebook profile)


It’s like this: Your muscles are comprised of individual muscle fibers. Making those individual fibers thicker is what muscle growth is. Any effective bodybuilding system MUST be designed in such a way that FORCES your body to increase the diameter of those fibers.

This is EXACTLY what THT does, and it does it phenomenally well! Yes, you’ll see a visible difference in muscle size in a matter of weeks with THT! Sound good? Just input your details for your copy of the workout…



  • How many reps do I do?
  • How many sets do I do?
  • How many days per week do I train?
  • What specific exercises do I do and how do I do them correctly?

I’ve covered ALL of those questions and more in the THT training book. You’ll know exactly what to do and how to do it from day 1!

“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”

“I’ve been using THT training for a couple of years now and it has totally changed the way I see training and eating. I’ve gone from a huge fat 19 stone, to a trim 15 stone with loads of extra muscle. You have changed my life…thank you.” Chris Brett Stewart (his facebook profile)


Curtis-&-SteveMany soldiers stationed all over the world follow THT! Curtis Weaver & Steve Stone are in the U.S. Air Force and are Explosive Ordnance Disposal Technicians. “I found your site 2 months ago & started THT training. 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.” [Full story here & yes they got tattoos in between pics]



Mark McManus Perfect-Body-Magazine-THT<= That’s me to the left. My name is Mark McManus, I’m a certified trainer and owner of one of the world’s most popular bodybuilding blogs – MuscleHack.com. At the time of writing, MuscleHack has around 65,000 subscribers. And you should be next!

I’ve been a featured author in major publications like Iron Man magazine and Perfect Body magazine as an authority on building muscle and fat loss.


During the course of my almost 10-year research into fat loss and muscle building, I stumbled upon some extremely POWERFUL techniques. I’ve put this all together into what I whole-heartedly believe is the BEST system of the planet for packing on muscle mass – Targeted Hypertrophy Training.

Why should you trust me? The purpose for me isn’t to get rich; it’s to build a community. I’ve written around 500 free articles. Created numerous free videos, provided free support to readers via blog comments, facebook, email, and on our forum. More importantly, I give the THT workout away free for anyone who wants the real TRUTH about building muscle.

But at the end of the day, you don’t have to believe me. Look at the the testimonials. Even better, try THT and be blown away!


“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. I went to the water park and when I took my shirt off, [my wife’s] oldest daughter told me to put it back on. She said, “All my friends are checking you out…along with their Moms!” I busted out laughing.” Sean Alexander Brown (his facebook profile)




YES Indeed! Want some proof?


Myra Marshall Before and After

“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.


Muscle Hacker Lisa Hauliska

“I spent my off season on the MANS diet and followed your THT workout. I cannot tell you how many people I refer to your site! Some don’t believe that’s “all” I used this last year to get where I am, but I tell them, yes it is!” Lisa Hauliska.


Brandi McAtee“I found the MuscleHack site in January of this year (2011). 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. This is Brandi’s Facebook profile (and this is her Fan Page).


mark-mcmanus1I take your hand through this. There is no room for guesswork. This is a scientific, precise system for packing on muscle fast…and it works!

MuscleHack is a friendly, helpful community. I’d love you to be a part of it. We’re all here to help, guide, and cheer you on to success!

The bodybuilding orthodoxy tells natural lifters to expect 3-5lbs of muscle growth in a year. Thankfully, that’s just not true! And now, as a Muscle Hacker, you can experience rapid gains in size and strength for yourself! Free!



If, for some strange reason, you STILL haven’t entered your details for your FREE copy of the THT workout, here’s some more proof of the sheer POWER of this training program…


markhouse“At 45 years old and 297 pounds, I decided it was time to transform. I needed to learn more and found your site from Brandi McAtee, NPC Competitor, who highly recommended it. I downloaded your THT workout program to learn as much as I could. Thank You for your free programs and for keeping it REAL!!” 45 year old Mark House from Princeton, NJ, USA. For verification, this is his email ( mark [at] homeemail.org) and this is his facebook profile.


ERIC-BEFORE-AND-AFTER“Just finished 10 weeks of THT. Great results. I weighed 63kg at 15% Body Fat (in the before pic). I weighed 69Kg at 12.5% (in the after pic). Huge difference. Thank you once again Mark!” Eric Leroyer, 20 yrs old. Note: that’s a 13.2lb increase in body weight with a 2.5% drop in body fat at the same time!


“I am living proof of the point you are trying to get across. Like you, I sport a six-pack all year-round and continue to progress in lean mass gains. I weighed in at 153lbs when my training days began. I am now in the low 180′s. I did a bodyfat check this morning: 8.7%. Not bad, especially when you are still putting on size. I cannot thank you enough, Mark, for your thorough guidance. I am sincerely grateful and deeply honored to join the ranks of your success stories! Keep inspiring us, Mark. You are an icon!” Craig Moody, 27 yrs old. Miami, FL, USA.

    I have to say thank you! I started doing your 5 day THT split a few months back and it’s been the perfect workout. I bought and tried countless others (Stronglifts 5×5 caused major injuries and sent me to the orthopaedist.) And now after buying lots of ‘diet’ plans (Xtreme fat lost, Burn the Fat, 3-week diet, and others) I finally decided to give TSPA a try. At first I thought, “Huh, another PDF that’s going to say the same thing, doesn’t last, and isn’t sustainable.”. But with your guarantee I went for it. WOW, I’m glad I did. I’m an analytical kind of guy so this really resonates with me. AND, I’m not hungry – the proportions of nutrients hits the sweet spot for my body. So it’s been two weeks now and although the scale is just starting to move, I look and feel better and my clothes fit better. Jeesh… I sound like a commercial…. But I finally found sustainable system. Thanks! I look forward to my six pack in 8 weeks :)

    I am a believer in your THT Program, no question. My only regret is not taking a photo prior to me starting the program because there is a huge difference in my body. Upper body is coming very nicely, calves are forming but my hamstrings and quads are a little slow in shaping. I am not giving up, pressing forward with even more determination.

    Thank you for all of your articles and continued support!

    The Dragon Lady is Reborn!!!!


  • JaSoN December 17, 2013, 10:04 am

    Mark, you’ve taken me off your testimonials page, Jason from jersey, ectomorph which gained a good size using your program, i see the article is still there though, thanks bud, i would have been stuck if it weren’t for your knowledge. ive gained another 4 kgs since that article!!

  • Mark McManus December 17, 2013, 11:32 am

    @Jason. I just checked and the post was placed into the wrong category type, my bad. Just fixed it and if you click on the testimonials tab and scroll down, you’ll see it near the bottom. Thanks for the heads up.

  • Mark McManus December 17, 2013, 11:33 am

    @Peter. Very happy for you, buddy. Great to see yet another person finally succeed after years of wading through the mountain of bad information out there.

  • Mark McManus December 17, 2013, 11:34 am

    @Catherine. Yes it’s always fun to look back at old pics and see the huge difference. Keep up the good work!

  • Ric December 17, 2013, 12:11 pm

    Hi, Mark, Just a question though on the HIT cycle. How do I progress with the weights? Do I need to add more weights if I meet the required reps the following work-out day?

  • Mark McManus December 17, 2013, 1:41 pm

    @Ric. Any time you hit the top of your rep range on any set, you know you have to lift a bit heavier on that set next time.
    So let’s say you’re working on the 8-12 rep range and get 12 reps on your set of preacher curls, next workout lift a little heavier. (5% – 10% heavier is good).

  • marianne December 17, 2013, 7:09 pm

    I just love this site its amazing how simple it has all become without having to be at the gym 24/7..thanx for the inspiration and keep up the great work

  • Mark McManus December 17, 2013, 10:39 pm

    @Marianne. Many thanks for the kind words 😀

  • Kenneth Raymond December 18, 2013, 8:31 pm

    Hi Mark I use THT for the base of my workout. I have changed it some to fit my life style.It has worked well for me i started at age 49 170 LB. After 14 months and now age 50 i am 210 LB. I feel better then i ever have in my life. Thanks for your help.

  • Mark McManus December 18, 2013, 8:57 pm

    Fantastic results, Kenneth. THT works for everyone!

  • sunshyme December 19, 2013, 12:41 pm

    Hi Mark. Hope it doesn’t sound like a silly question…but…you know when you do a work out and the next day you suffer from muscle soreness, is the amount of pain proportional to the amount of growth you’ve stimulated. So, suppose the next day you don’t hurt at all, does that mean you wont grow much. Or, if the next you’re in complete agony, does that mean you’ve stimulated lots growth.

  • lauyijunht December 20, 2013, 1:42 pm

    hey mark ~~ any advice or opinion in supersetting ??

  • Mark McManus December 20, 2013, 3:18 pm

    @sunshyme. You’ll get varying opinions on soreness from everyone, because of the fact that no-one knows for sure. I think it can be a marker for growth, but it’s only one and shouldn’t be depended upon for a definitive answer as to whether growth has been stimulated or not. What you need to focus on is training to failure each set and making sure that there is progressive overload each workout (more weight and/or reps). That’s the way to know for sure, not muscle soreness.

  • Mark McManus December 20, 2013, 3:20 pm

    @lauyijunht. Yeah they’re a bad idea (unless you are more specifically referring to an ‘extended set’). Read this for full details… http://www.musclehack.com/why-supersets-arent-so-super/

  • Ric December 23, 2013, 4:44 pm

    Hey, Mark. What’s your take on pull-ups/chin-ups? Do you recommend it to be included in THT? If so, what exercise from the recent THT Volume and HIT program should be replaced?

  • Mark McManus December 23, 2013, 8:19 pm

    @Ric. Yes chin ups are recommended on THT. The full THT Exercise Bank is here http://www.musclehack.com/targeted-hypertrophy-training-exercise-bank/
    Since it is a compound movement and we only switch a compound movement for another compound movement, or an isolation exercise for another isolation exercise in THT, you can switch this for close-grip palms-up pull-downs. If you aren’t doing this exercise, simply add a couple sets of of chin-ups into your bicep routine.
