Pre-workout booster totally useless? Or an insider tip?

We will start with the product I recommend the most:

I am not an affiliate with any of these products and only mention them because they work. If you want me to review your product on this website, please leave me a message. I will be happy to answer any questions you may have about your product. Please note, these are not affiliate links; I just want to make sure that people can afford to get the best equipment they can afford. If you need any other products to get better at training, please don't hesitate to contact me. I am not one of these product marketing companies. I do recommend a few, and I don't always buy them. I recommend you buy the products that will get you where you want to go faster and better.

There's also some good news about the "new" Nautilus and Nautilus Training Program: I've got a lot of stuff I need to get ready for the upcoming winter season, including a large-scale indoor training program, so I decided to build a few new tools and equipment. This is the result of a lot of work and research that I've put into this project and a ton of research and experimentation that's taken place over the last few years.
