Bigger Leaner Stronger is the furthest thing from “bro-science,” halle-freakin-lujah.
Michael Matthews backs everything he says with scientific literature (to the point of being mildly annoying). This 2018 pilot study discovered that hypertrophy and strength benefits level off after five sets - making ten straight sets overkill.
Cavaliere offers his own take on GVT, but there’s not much scientific proof this training style works.
German Volume Training (GVT) isn’t necessarily better for lean gains. But if you have a favorite muscle to train (and we all do), it’ll be about 57-some-odd days before you train it twice a week. Sure, a once-a-week frequency can be just as effective as more frequent training, assuming your weekly training volume is similar ( 2021 study). There’s a sloooow lead-up to a twice-a-week frequency. We suggest holding off on this one until you have a few months of training under your belt. On top of being an insanely tough Athlean-X program, it’s also among the least beginner-friendly. Many rate it one of the hardest Athlean-X programs ever. If you’re still not sold on Max Size, you’ll likely be disappointed and out nearly $100. Bigger leaner stronger routine full#
There’s no way to tell who’s screenshotting an entire program before “returning” it for a full refund with digital-only programs.
Athlean-X has a no refund policy (sorry, suckas). But studies - like this one published in the Biology of Sport in 2020 - show that it’s no better for building strength or size than stopping a few reps shy of failure. Don’t get us wrong there’s nothing “wrong” with training to failure. But Max Size still thrives with the detail it provides - introductory videos, equipment lists, rep and weight-tracking tools, exercise demos, and “Instruxions” detailing the specifics of each exercise. The Athlean-X portal is still a few years behind in the technological sense.
This program comes with supplemental resources. There’ll be no doubt in your mind that you “did enough” and didn’t waste your time in the gym. On top of being drenched in sweat and ending each workout with jello-y muscles, it’ll drain whatever fuel’s left in the tank. Every Max Size workout is absolutely draining (mentally & physically). There’s also a “bonus” - “Size Swaps” for each meal for hard-gainers battling the scale. Stuffed inside this diet plan is 12 weeks’ worth of meals broken down by ingredient and macronutrient. The hidden gem of Max Size is the X-Factor meal plan. Better Leaner Stronger doesn’t stand a chance against the Max Size meal plan. The negatives, slow reps, supersets, German Volume Training, and finisher circuits can get your gains back on track as you overcome plateaus ( 2019 research). If you’re convinced you’re “built different” in the hard-gainer-type way, Max Size should finally spark growth. Really, you’re destined for results with this one.
A biomechanics, exercise science, and physical therapy genius, the Athlean-X founder is also one of the most well-respected trainers in the fitness world (aside from, y’know, the whole “fake weights” saga).
