I have enjoyed my experience in Heavy Duty Nation on several levels. The e-books & spreadsheets which Markus has put together are great as they answer most questions plus help readers adjust for their situations such as age, conditioning level, years of experience in High Intensity Training (HIT) styles, and more. Markus answers our questions in the community, has great Q&A calls, is helpful & motivating in emails, and he also leads by example. Hopefully anyone joining will benefit like I have.

I joined a few months ago and it was extremely well worth it! I remember watching the videos of Mr. Mentzer himself training a young man back in the '90s before his untimely death. Well, that young man was and is Markus Reinhardt and we have direct access to him here! He is awesome at responding to questions and gives great "realistic" training advice to me on a personal level being over 60! Anyone interested in training HIT style owes it to themselves to join Heavy Duty Nation.

I’ve been a member for nearly one year now. Being a devout follower of HIT protocol for most of my life (Jones, Mentzer, et al), only old audios a very few videos exist of these early pioneers espousing these ideals of exercise science. Heavy Duty Nation is directly operated by the only direct descendant of Mike Mentzer. Where Mentzer improved upon Jones’s hypothesis, Marcus has evolved Mentzer’s early work into the next level for a modern audience. It’s all here.
