Welcome to Strength & Science!

About this site

The content on Strength & Science is about one thing and one thing only: the evidence-based approach to fitness. No fads, no ego, and no speculation. If something appears on this site, it's because there's good evidence to back it up - either directly from the scientific literature, or based on a sound line of reasoning. Don't take my word for anything.

If you appreciate what this site stands for, please spread the word. It's not about me - it's about the skeptical approach to fitness. It's about believing something and using practices because they are verifiably accurate - not simply because someone says so.

If you think that's a better approach to strength and fitness than the common approach in the main stream of the fitness industry, welcome aboard. I think you'll like it here.

Squats are not Hip Dominant or Knee Dominant. Some Biomechanical Black Magic.

What you’re getting yourself into: -2200 words.  8-10 minute read time.  If you’re in a hurry, you can skip on down to the “Practical Takeaways” and save the dense stuff for later. Key Points: 1) The origins and insertions of the hamstrings and rectus femoris allow them to extend the hip and knee simultaneously, even though their actions oppose each other. 2) Two joint muscles allow force from single joint muscles to be transmitted to joints they wouldn’t otherwise be able to effect.  For example, the rectus femoris allows the glutes to help extend the knee. 3) You can put […]

The Science of Steroids

Steroids are a very taboo subject in our culture. They are Schedule III controlled substances, meaning they are illegal to own without a prescription, and illegal to distribute unless you are an MD. Furthermore, they are banned in almost all athletic competitions (with the exceptions being some untested strength sports). This is not meant to be read as an article condoning steroid use. They carry numerous short-term risks (high blood pressure, high cholesterol, liver toxicity, etc.), with the potential for long-term risks (atherosclerosis, infertility, hypogonadism, etc.) dependent on the particular compounds used, the dosages, and the duration you take them.

In defense of program hoppers; DUP revisited

Ever since I wrote my article on Daily Undulating Periodization (DUP) a couple months ago, I’ve had a nagging feeling that something wasn’t quite right, like something was a little bit off.  (If you haven’t read the first article, or if you don’t know what DUP is, I’d suggest you check it out first) Physiologically, I’m not sure the rationale behind DUP totally makes sense of the situation.  Not that it is entirely nonsensical, but I had a feeling that the effects and benefits couldn’t be explained solely by the physiological mechanisms proposed. The basic notion is that your body […]
