One pound of fat is equal to 3,500 cal­ories, so for every pound of fat you want to lose, you need to create a caloric deficit of 3,500. Based on what we know about calories in versus calories out, this deficit can’t be achieved in a day, or even a few days. To put itRead more »

It might come as a shock that the Core Envy program does not include crunches! I’ve intentionally omitted crunches because they don’t utilize a significant percentage of your core musculature.

What Is a “Core Workout” Anyway?

Core Envy by Allison Westfahl CNV

A good core workout works a lot more than just your ab muscles. When I talk about the foundation for your core, I’m not referring just to the intri­cate musculature beneath your abs. Your glutes and hamstrings are also involved. These muscles are traditionally categorized as “lower-body” muscles, but they serve a dual function inRead more »

You Can’t Lose Much Fat Doing Crunches

Core Envy by Allison Westfahl CNV
