The brain normally derives almost all of its energy from glucose but can turns to the ketone bodies if needed. It is the only organ that's so picky. Yes, around 50lbs since 5/14 but been stuck the last six months trying to loss the last ten pounds. Was halfway until I caught a cold earlier this month and being lax over the…

There are two anaerobic (without oxygen) pathways: non-aerobic glycolysis and phosphagen system. Lactic acid or blood lactate is a by-product of the non-aerobic glycolysis. If you are generating a lot of lactic acid, your intensity is too low for HIIT.

25 second power or less, L7 or neuromuscular power, is the norm for cycling. Typically it's 15 second power. 30 second power in L6 or anaerobic capacity which >= 121% of your average power in a 60 minute time trial. It is not HIIT. Do a functional threshold power test then you can tell if you're in the right training level…

I wished the Timmons regimen was never publicized or started in the first place. Jamie Timmons' hypothesis was/is misguided in the first place (at least applied to the general public) and his hobnob with Michael Mosley in the BBC Horizon programme in February 2012 only serves to mislead (disgusting in my book).

It's a matter of determining intensity or work effort. Most people, including myself, are really bad at it especially when your red lining. It takes practice and subjectivity to apply RPE when doing steady state tempo (up to 80-90% LT) but that goes out of door when there is no effective matrix to track for 20-30 seconds…

Heart rate monitor are useless when doing HIIT. The rep and rest period, ~60-90 seconds, will be over before your heart rate ramps up (~2 minutes average). It's losing proposition for the following rep as your heart rate will never settle to reflect the intensity. Anyone saying otherwise needs to hit the books. By the way…

OP - like other have stated, you are underestimating your intake, and as a consequence of your improved fitness your workout is less effective. See http://sportsscientists.com/2010/01/exercise-and-weight-loss/ for a better explanation of the adaptation that is happening. There three sources of ATP, energy currency used in…

As designed, Tabata (1E1 protocol), the intensity is at 170% of VO2Max for 20 seconds (energy derived using the phosphagen system) with 10 seconds of rest for 4 minutes. It's a VERY VERY difficult workout. It's one of four HIIT regimens. The major differences are primarily in the work/rest ratio, total duration of core…

45 hours & hope to reach 7k miles for the year.

At first, a month or so, but now I just use it to cover errors and occasional indulgence. I walk 2.3 miles during my morning break on most weekdays in around 30-35 minutes depending on the mood. Try cycling. It's lot easier on the knees and there are plenty of ex-runners that took up the sport because of running is to hard…

No fluctuations but did eat up after the procedure. The liquid mix wasn't that bad.

I started May 2014 around 212# and been at 163# since summer (5'8"). I need to drop another 10# but it's been hard with the intensity I'm doing; I got tired being constantly dropped on group rides so been focusing on power at expense of weight loss. Over the winter I'm switching gears and hopefully get down to my old…

Tabata? Tabata's study, IE1 protocol, consist of 20 seconds of ultra-intense exercise at an intensity of about 170% of VO2max followed by 10 seconds of rest, repeated continuously for 4 minutes (8 cycles) on a mechanically braked cycle ergometer. Why are you doing this? Or are you referring to the popular culture, "Tabata…

I ride on 28s and can take it on the dirt but it's not ideal. With respect to grip both will have similar characteristics although as it gets narrower there also less traction. Flat resistance is also at play. The handling of the two bike style is where the major differences laid. Being more upright, having a longer wheel…

First find out what your VO2Max is and make a note how that feels. Select an exercise (aerobic of course) and hit your VO2Max or above (neuromuscular) on each work interval. Allow 1:1 ratio between work and rest and do a few intervals (say 3-5). Do two to three sets and allow 2:1 or 1:1 work and rest ratio between sets.…
