Kurtis Frank on the Best Pre-Workout Supplements

Written by:
Kurtis Frank on the Best Pre-Workout Supplements

If you want to know what pre-workout supplements are, why people use them, and what works best, you want to listen to this podcast.

Ten years ago, pre-workout supplements were for the unhinged looking dudes in the gym who nobody made eye contact with.

You know the type: steroids, stringers, water jugs, strutting and peacocking, and the like.

Back then, the pre-workout space mostly consisted of products like Craze, Jack3d, and Detonate (all of which have been banned, by the way) that contained mega-doses of amphetamine-like stimulants and little else.

Fortunately, times have changed, and now we have pre-workout supplements that contain lower levels of much safer stimulants plus clinically effective doses of safe, natural ingredients scientifically proven to enhance performance and muscle and strength gain.

That’s why people who take their training seriously aren’t asking whether they should take a pre-workout supplement anymore but instead which they should choose and why.

And that’s what Kurtis Frank and I talk about in today’s interview.

In case you’re not familiar with Kurtis, he’s the director of Research and Development for my supplement company Legion Athletics as well as the co-founder and former lead researcher and writer for, which is the premiere online resource for science-based information on supplementation.

Here’s a sneak peek of what you’ll learn in this episode:

  • What a pre-workout is
  • Ingredients that do and don’t significantly improve performance
  • How much you need to take of these ingredients to see benefits
  • The pros and cons of including creatine in a pre-workout supplement
  • And more.
