Max Size Review
I have thoroughly enjoyed this program and the results from it. The variety of exercises and the intensity of the workouts pushes me every time and keeps it interesting. I would highly recommend Max Size to others.

Great workout for more strength
I could definitely feel the difference in overall strength after just a few weeks of this program. It was nice to get some of the more classic lifts into the routine. It’s a fun one!

Launch for gains
Great program with strategic and comprehensive approach for developing physique. Good lessons for using different methods. Pretty demanding also. Weeks 5-8 were exhausting for body, last 9-12 for mind. Gains guaranteed. I’m living very busy years and had short training pauses during this program, but still I progressed very much.

Solid Program
I used this program specifically to get back into weight lifting and muscle building after taking a few years off. I wasn’t really concerned about fat loss or cardio at the time, but with this program you definitely are getting a full body workout. It’s great for the beginner, as well as the experienced lifter looking for a change in routine that might have gone stale. I also enjoyed using the site to keep track of my notes for each workout. It keeps track of your prior workouts to ensure you are progressing. Overall, if you follow the program, do the workouts the way they are intended, you will see gains.

Grueling but good!
This program is no joke. I completed AX-1 and AX-2 prior to this, and I liked them but they weren’t as challenging as I expected. This program (Max Size) is exhausting, with most sets going to failure and some performing ISO holds after that. Just trusting Jeff and doing what he says to do (as I usually do), I got results. All in all I liked the program and would suggest for anyone wanting to try it that you ensure you have your nutrition dialed in and allocate ample time for rest/recovery because you’ll need it!

Max Size Works
I am a hard gainer. I have seen the best gains I have ever had and I am 63 years old with Max Size. Make sure you have your diet dialed in and get plenty of sleep because your going to need it to recover after each workout.

Surprisingly well rounded and great results!
This program was very challenging for me. BLUF between this and MAD shred which I did first, I dropped 4″ off my waist and went from 16% bf to about 10%. Best of all I feel like I’ve gotten better at engaging shoulders and back muscles like I never have before. Don’t be intimidated, treat every workout like a practice session and you’ll be amazed at how much you learn. And my muscles, particularly chest/arms/shoulders are a lot more defined too. The 3 distinct phases were uniquely different but really flowed well together. Best of all, my conditioning is still decent. Give it a go!
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!
