      <description>Dr. Stacy Sims is an exercise physiologist and nutrition scientist whose mantra – &quot;women are not small men&quot; – has reshaped how women approach their health.

Recorded live with a studio audience, we challenge the conventional wisdom around fasting, cardio, and calorie restriction.


In its place, a playbook calibrated for female physiology – heavy lifting, fed-state training, circadian eating, and a new relationship with perimenopause.
Stacy is a force. Enjoy!</description>

      <content:encoded><![CDATA[<p>This podcast re-affirmed in many ways what we already knew, but with even more science to back it up.</p>
<ul>
<li>Lifting heavy is even more important than we thought especially for women</li>
<li>Creatine...</li>
<li>True high intensity is crucial - F45 and anything where you&#39;re moving for more than a few minutes at a time is NOT HIIT and is actually bad for you</li>

      <description>the body runs on three energy systems. phosphagen for short and brutal, glycolytic for the middle burn, oxidative for the long stuff. train them all.</description>

      <content:encoded><![CDATA[<p>Ok, spoiler alert, this post is me geeking out a little bit about training intensity, (concerning cardio) and while I find this kind of stuff pretty cool for some reason not everyone else does (heads up, not a good topic for your typical night out….)</p>
<h2 id="how-our-bodies-create-energy-and-allow-us-to-exercise-do-pretty-much-anything-i-e-the-3-energy-pathways">HOW OUR BODIES CREATE ENERGY AND ALLOW US TO EXERCISE/DO PRETTY MUCH ANYTHING (I.E. THE 3 ENERGY PATHWAYS)</h2>
<p>Keep in mind that the process of creating energy is way more complicated than this, but essentially the body converts substances within our body (such as food) to useable forms of energy and in order to do so there needs to be oxygen (among other things) present. Our bodies have 3 different methods of creating energy and the one we use at any given time depends on the energy requirements of the activity we are doing at that moment. The Three Methods (pathways) are…</p>
<ol>
<li><strong>The Phosphagen Pathway:</strong> fuels intense exercises which are only sustainable for up to 30 seconds (think maximum effort sprints)</li>
<li><strong>The Glycolytic Pathway</strong>: for when we engage in moderate-to-high intensity exercise lasting approximately 2 and a half minutes but not longer (running around a 400m track for time)</li>
<li><strong>The Oxidative Pathway</strong>: for low-to-moderate intensity exercises that can be sustained for long periods of time (running a 5k, a 10k, a half marathon….you get the idea)</li>
</ol>

<h3 id="what-this-means-re-cardio-amp-training">WHAT THIS MEANS RE: CARDIO &amp; TRAINING</h3>
<p>The first two pathways (Phosphagen and Glycolytic) are anaerobic, meaning that they use oxygen quicker than our bodies can supply it (not that our bodies don’t try, think back to your breathing last time you did some sprints). It is because of the demand for oxygen..</p>
