Squat Science: Debunking Myths About Foot Position, Depth & Muscle Activation

28 minutes

Unlock the secrets behind squat biomechanics in this must-listen episode of the "NASM CPTPodcast" with host, and NASM Master Instructor, Rick Richey.

Whether you’re a fitness veteran or just starting your strength journey, this episode dives deep into the science—and myths—about squats, backed by the latest research.

Curious about why your torso leans differently during squats, or how changing your foot position impacts muscle activation?

Rick breaks down the impact of tibia-torso angles, foot position (should

you turn your toes out?), and squat depth on your muscles and overall

performance. Learn how “butt wink,” squat depth, and even partial squats play a role in hypertrophy and athletic performance—and what matters most for avoiding injury.

Packed with evidence from studies like Barack et al. (2011) and Strab & Powers (2024), this episode smashes old rules and reveals how to tailor your squat technique for optimal results, safety, and YOUR body’s limitations.

Worried about knee pain, back issues, or if deeper squats are better? The answers may surprise you!

Plus, get actionable tips on how to assess and improve your range of motion, how personal anatomy affects squat form, and why consistency often beats perfection in your training routine.
