Muscle Metabolism

October 25, 2011

Here’s a great comment by ‘Gokul’ to explore some of the facts behind muscle and metabolism. My comments in RED

I think you are wrong Brad.
Take 2 hypothetical males of the same height and frame size. 1st guy(thin) weighs 60kgs (132 pounds) and has 6% body fat.
2nd guy(muscular) weighs 80 kgs (176 pounds) and has 6% body fat.
Now according to Katch mc ardle’s formula: (RMR = [LBM (KG) x 21.6) + 370])
1st guy BMR is 1588 cal.
2nd guy BMR is 1994 cal.
Lean mass of 1st guy from Katch’s formual 56.4 kgs. (124 pounds)
Lean mass of 2nd guy from Katch’s formula is 75.2 kgs. (165 pounds)
(That’s a 41 pound difference, very difficult for two guys of the same height to have a 41 pounds difference in skeletal muscle mass and both be very lean.. but I’ll let it slide)
Now assuming that both have similar size internal organs which is a safe […]

Warrior Fit Testimonials

First, I want to say thank you for convincing me to do Tabata! I was struggling to lose weight and Finally I found something that helped! I really appreciate your coaching! - Craig T.

Ever since I was convinced to do Tabata I have seen huge results, I lost 6 pounds and gained energy in the first 3 weeks. I have been working out for 3 months before I decided to do Tabata and I struggled to lose weight. At first I thought "How am I losing weight by bringing my heart rate up then cooling down then bringing it up again?" I don’t know how it works but it does! Thank you!! - Theresa F.

The first day of Tabata, I wondered WHAT AM I DOING - I AM 56 !! Five weeks later I knew that it was what I needed. I learned that I could push myself well beyond my comfort zone and feel good later. I have a marked improvement in physical as well as emotional endurance. - Lyn C.

When I was first told about Tabata I was very excited from the word go, however that excitement stemmed from the fact that I had no clue what it meant. I missed the first week of class b/c I was traveling for work so when I came in during the 2nd week I had some making it up to do. It was hard at first b/c my body wasn't used to working out at such a fast pace, but once I got into a rhythm I started to feel very good. These classes are no joke. If you stick with it you will leave there feeling stronger, healthier and overall better about yourself and what you've accomplished. I would recommend these classes to anyone. Darrin is a great trainer and he'll keep you going with his energy. - Jami L.
