bike circuit in ATL

 At Roya's house this week.   Yesterday did the usual ~ mile circuit with 3 hill climbs 4x.  Also, resistance work and a 2 mile hike after dinner.   Fat is coming off slowly. 

With so many short hills and ups and downs, HR graph looked pretty weird.  None of the hills were long enough to generate a high HR.   Just a dozen short sprints.

Bike ride

6.8 miles

Max HR - 170

Avg HR - 142

Roya has a pullup bar so I brought my hanging ab straps and ab wheel.  

Roya got bummed by her reading on my Hume scale showing her bodyfat at 26% and her 'metabolic age' at 61.  (I'm at 13% BF and m-age 48).  A lot of that is genetic I think, and the 'metabolic age' is basically a algorithm.  

Hume's "metabolic age" is based on basic metabolic rate (BMR) -  number of calories your body burns at rest—compared against the average BMR for others of your same chronological age, gender, and height.   Hume platform bases this metric on several specific physiological variables, particularly body composition.  Lean muscle mass, total body fat, and visceral fat. (Muscle tissue requires more energy to maintain than fat, which directly raises your BMR).   Of course this proprietary algorithm is probably not accurate, consistent, and is only as good as the measuring tool, which isn't very good.  It's just a general indication.   The scale weighs a bit more than the beam balance (physicians scale). 144.1 on the Hume, 143.5 on the beam scale.  

Going to hit the resistance today.  

A friend of mine who is a retired 2x World 400m Masters champion in my age group just completed this enormous bike climb in the UK.  95 miles including 6 climbs with a total ascent of 2332 meters.  He did it in about 6 hrs.  I can't imagine.  Just the first climb in the series of 6 is about what Raccoon mtn is.  He retired from track after a very serious knee injury and surgery, probably more serious than mine.  Amazing that knees can handle such severe biking but not sprint training.  Sprint training is very specialized.
