Burst Training for Muscle-Mass Gaining

Q: You recently referenced Mike Mentzer, and I’m wondering if you guys have ever trained with his HIT style. One-set-to-failure training seems to work for some people, and I know Mentzer’s training evolved into that after he stopped competing. Have you tried it or something similar?

A: One of Steve’s early influences was Mike Mentzer. He trained with Mike’s Heavy Duty style in his 20s, and even won his first bodybuilding contest using a Positions-of-Flexion version of Heavy Duty that he devised (more on that below)… [Read more…]

Ultimate Muscle Size: Slow-twitch first—Fast-twitch burst

Q: Doing one high-rep set first before heavy sets is your MMX method for more fast-twitch fiber activation and growth. Isn’t that first high-rep set just a glorified warmup set?

A more accurate word is “focused” or “targeted.” Why? Because you get the benefits of multiple lighter warmup sets with that one slow-twitch-exhaustion (STX) set, using 20-plus reps to failure… [Read more…]

No B.S.: 4X for Mass-Building Success—Even Mentzer Would Confess

Q: I’m a big believer in Mike Mentzer’s Heavy Duty system of one all-out set to failure for each exercise. That’s why I think your 4X method is total B.S. Mentzer cited studies and found from personal experience that intensity is the key to muscle growth. With 4X you’re using lighter weights and not going to failure, which wastes a lot of sets. It can’t work, and I think you should feel ashamed for promoting it as miracle mass-building system.

A: We didn’t say it’s a “miracle” system (although some trainees have said it worked mass miracles for them). We simply said that we GUARANTEE that our 4X programs will build NEW MASS for just about anyone. We’re absolutely positive of that because it’s got ALL the critical components to trigger bigger gains quickly—and that includes intensity (we think Mentzer would agree as you’ll see, and that’s no B.S.)… [Read more…]
