Innovative Rep Schemes

No one rep range is best for building muscle. Low reps with heavy weight, high reps with light weight, and everything in between – it takes all of them properly intertwined to maximize size gains. JimStoppani.com programs utilize all major periodization models to keep the reps changing and your muscles growing.

Intensity-Boosting Techniques

You can’t build new muscle in stubborn areas without pushing the boundaries of intensity and getting creative. Dr. Stoppani does this through unique applications of time-tested training tools like supersets, drop sets, rest-pauses, staggered sets, giant sets, pre-exhaustion, and many more.

Variety by Design

A boring program is usually an ineffective one. Yet senseless change in the name of “muscle confusion” is a sure way to halt progress. Dr. Stoppani incorporates variety in all areas of program design – but it’s purposeful variety, not random, and it’s all rooted in scientific research. When the variety is intelligent, you get sustained progress and fewer plateaus.

Nutrition And Supplements

Build more quality muscle with simple yet effective meal plans and top-selling supplements.

Adding size to your frame is as simple as following Dr. Stoppani’s 9 Muscle Building Rules and implementing any of his step-by-step meal plans. And we’re talking about lean gains here, thanks to optimal macronutrient guidelines that can be customized to your individual body type. Enhance your diet with the JYM System (Pre JYM, Post JYM, Pro JYM), JYM Support Stack (Vita JYM, Omega JYM, ZMA JYM), and specialty products like Mass JYM and Alpha JYM to promote full muscle recovery and maximize results.
