As Tough As It Gets
This workout program sincerely made me revaluate my level of strength and fitness. The results have been great and even though it took me a few attempts to complete it the journey was worth the struggle. Truthfully, this course made me feel insecure about my ability – the final month is grueling and I had to bring my numbers down in order not to spend hours in the gym and to complete it, if you follow it to the letter you’ll see what I mean. Get this program to push yourself harder than ever before and good luck to you, my friend: you are up to the challenge

I Got BIG
This program has been revolutionary for my growth! It was the first program I ever committed to a few years back and I have gone through it with increased weight and strength 3 times. I have put on 30 pounds of muscle in the last 4 years and it has been because of this program and my commitment to other programs by Jeff! I started at 145 pounds and am now maintaining 175 pounds with a relatively low body fat percentage. 10 out of 10, would recommend! In fact I have to all my gym friends. Can’t wait to see my progress another year down the road!

Amazing Gains and Got Lean!
Man, this was intense. I’m still 6 days out of completing it. But I got some serious gains and also got somewhat leaner. The only thing I advise is that if you’re not used to high volume / intense workouts, do some high intensity workouts with a lot of reps in the major exercises to avoid any risk of injury. Well, the coach will say if that’s better but that was my scenario. Still managed to make it and got the gains!

Max Size Works!!!
I have been training consistently, however the weight I used is below the recommendation (eg Recommend 6 RM maybe at 20kg but I used around 13-15kg), however, I still experiencing good growth in my muscle and at times I have to break (1-2 weeks) when I’m on holiday, my muscles retain and getting back to momentum was easy. I am planning to repeat the cycle again.

MAX Size: Great Hypertrophy High Volume Program
Did MAX Size after already having done a few programs (AX-1, AX-2, Total Beast, & AAM). Thought it is a great hypertrophy based high volume workout. I personally don’t train high volume hypertrophy work a lot so it was a nice change of pace from what I’m accustomed to. Gained a few pounds of muscle in the program. Could’ve added more weight if I ate more of the size focused meals, but would rather slowly add lean muscle than a bunch of quick weight that’s mostly fat. It would’ve been nice if there was a 3-4 workouts per week option as that’s my preferred training frequency. This program was more of 4-5 times a week, which was again a nice change of pace for me personally but I would’ve been nice to have a 3-4 times a week option. I like how the program is pretty flexible and most of the workouts can be done from home if you have a set of heavy adjustable dumbbells, pull up bar, bands and a physioball. You really only need a BB and squat rack for some of the leg days. Enjoyed the German volume training based phase the first month. First exposure to that training style and did it twice. Loved the arson phase in the second month and probably was my favorite month in the whole program. Only critique in the arson phase was that some of the workouts were a bit long, especially the leg day. I can normally complete any Athlean-X in an hour or less but some of the leg days in the arson phase took me 1.5 hours with strict adherence to the sets and rest protocol. Setup and going from area to area in the gym probably adds some time, but felt like the leg day in arson phase was unusually long. Love the five alarm finishers! The arson phase in general reminded me a lot of month 2 in AAM. Didn’t really care for the stretches and flexes in between sets in phase 3, but appreciate doing something different. LOVED the athletic pillars in phase 3 and they reminded me a lot of the Iron Will challenges and SAQ days in AAM. I will definitely do Total Beast (all-time favorite AX program) and AAM again, but not sure if I would do this program again. If someone has already done a few AX programs and is looking for a high volume, hypertrophy focused program MAX SIZE is definitely worth trying once. Looking forward to trying the sister program MAX Shred sometime as well as Old School Iron. Overall, MAX Size is another great program in the AX library and worth checking out if you haven’t done it yet.

You’re going to get huge gains
This program pushed me harder than I’ve been pushed before (first Athlean program). I’ve been lifting since I was 14 (now 31) and have yet to push myself to this level of muscle exhaustion. The ignition series at the beginning of this program added a lot of strength by itself. I had never done 10 by 10 before. Absolutely loved it

Genuine changes
This is my second Athleanx-X program. Just like the first one I tried, this program is phenomenal. I’ve been a ‘hard-gainer’ my whole life. With this particular program, I’ve seen more genuine changes and made more genuine gains than I ever have in my life. To be clear, I saw genuine changes and gains with the first program I did (Beaxst), but I wanted to try this program because I wanted to see if I could actually build real size. The last 25% of this program is where I really started to see the big changes. I was kind of shocked by how well it worked. I have had a hard time putting on muscle my entire life, and I’m 37 now, so I firmly believe if you follow the program closely and you go hard, you’re going to see real size changes. What I love about this program too is that Jeff makes sure you are still getting conditioning and athletic training in as well. This is why I’ll always be on one of the Athlean-X programs. I feel confident going into my 40s with these programs in my back pocket. I’m just bummed this wasn’t available in my 20s.

Max Size Review
Max Size was my first Athlean X program I have purchased. Over the years I have tried some of the Athlean X workouts on YouTube. Max Size was an excellent program from start to finish. Every month the program changed and got harder as things progressed. Overall I would recommend for someone looking to put on muscle.
FAQ'S
The program average 5 days per week with each workout clocking in between 10 minutes (for some intense conditioning work) to about 60 minutes (depending on your ability to withstand the finishers!)
Both Max/Shred and Max/Size will require equipment. While there is a great deal of bodyweight training programmed, you will need the basics for a home gym such as some dumbbells, an adjustable bench, resistance band, pullup bar, and a barbell to complete the exercises as they are programmed.
That said, as with AX-1, exercise swaps can be made to overcome the lack of a barbell with dumbbell adaptations coming in as suitable replacements.
The Max/Size program is not designed to be fit into the existing AX-1 schedule or any other A-X workout, as it is a stand alone program with the perfect amount of volume included to achieve the goal of maximum fat loss without loss of strength or size.
Absolutely!
There has been a dramatic shift in recent years towards heavier training being advocated for women. This is great! That said, in a rush to do so, poor programming has resulted in many women getting hurt and injured from the improper guidance on how to do that. Max/Size provides you with the safest, most structured approach to lifting heavier so you can add lean toned muscle without sacrificing femininity. The program can also be used in succession with Max/Shred to reap the benefits of both maximum fat loss and lean muscle development should you choose to do so.
The Max/Size and Max/Shred programs are not designed to be performed at the same time, as they are stand alone 12 week programs, allowing you to focus your effort on one goal at a time. That said, they were designed to build off of each other and work perfectly when done in succession!
Whether you want to focus on fat loss or lean muscle gain first, the other program will smoothly pick up where one leaves off allowing you to create your own physique over 24 weeks!
Max/Size is designed to do one thing better than any other program, build muscle.
That said, with it's strategies rooted in the science of muscle growth and ensuring the intensity in every workout is high enough to create it…Max/Size can help even the hardest of hard gainers to put on muscle. The importance of recovery is key, and often overlooked by those eager to pack on the gains. Not in Max/Size.
That is a term that is often relied on to place an artificial limit on what you can achieve with your physique. Most of the time, even the most seasoned of lifters find that they have another level of intensity that they simply have not tapped into (because it’s damn hard!).
Max/Size gives you no choice but to train in that realm…and in doing so, delivers results for anyone who dares tackle it!
