Host and NASM Master Instructor Rick Richey talks with guest Pete McCall about highintensity exercises and their impact on the aging process.

The two discuss McCall's book on the subject, how the research from exercisers in their 70’s has seen similar muscle enzyme activity as those in their 20’s. The discussion also includes hormone production, muscle fiber recruitment, and the safety concerns of agerelated HIIT programming.
