Week 1 Workout

Week 1 Workout

For physicians, the most exciting data from HIIT studies relates to improvements in insulin resistance which is the root of most chronic disease. We learned that glucose transporters (GLUT4) are “revved up”, increasing sensitivity to insulin. As we seek to reverse the diabetes epidemic, HIIT training is a welcome and especially powerful new tool (although we must not forget that resistance training carries it’s own weight in this regard). The benefit of HIIT first caught my attention when a partner pointed out the “sprint 8” study which showed a substantial increase in growth hormone with 3 twenty minute workouts per week. GH has been called the “youth hormone” due to its positive effect on skin, bones, muscles, blood vessels and fat burning. For this reason, it is sold in illicit clinics as an injection for improved athletic performance and “anti-aging”. Several well known baseball players could have saved themselves a lot of money and trouble by engaging in some high intensity interval training! Finally, we see variable yet sometimes dramatic improvements in blood lipids. HDL-C (“good cholesterol”) has increased up to 18% in studies, and I’ve previously told about my patient who lowered her LDL-P (LDL particle number) from 2000 (scary number!) to 600 (fabulous number!) She then became an evangelist who recruited many others into these workouts. Although I’ve not covered every known benefit of HIIT, this should be enough to encourage most anyone to give it a try. (Preferably with supervision for initial workouts and after being cleared by a doctor 🙂 ) We would love to work with you at VitalSigns!
