Listener Daragh finished his first Ironman - in 9:55:07 using Ben's Triathlon Dominator program. ----------------------------------------------------- Listener Q&A: As compiled and read by Brock, the Ben Greenfield Fitness Podcast "sidekick". Audio Question from AJ: He is a competitive cyclist and mountain bike racer. His weakness is his gut. Doesn't do well on solid foods and has switched to liquid calories. Has trouble with diarrhea especially when he is travelling. Has diarrhea a few times a week. Looking for causes and solutions. ~ In my response to AJ, I mention the Genova Parasitology test. I also mention the Specific Carbohydrate Diet, and the free Specific Carbohydrate Diet e-book. Audio Question from Carlos: Question about HIIT. Most programs says you should go high for 30 and low for 30 seconds. Would it better to use a Heart Rate Monitor and go hard/fast until I hit 180 bpm and then go slow until I hit 140bpm? ~ In my response to Carlos, I mention the complete guide to interval training article. Audio Question from Chris: In the past Ben has mentioned playing tennis. He is curious - what are the exercises and training routines that you have found to help with knee health and joint health when it comes to tennis? What training tips would you have? ~ In my response to Chris, I mention Capraflex. Audio Question from Jennifer: She has dropped grains out of her diet (except for quinoa). Does plenty of exercise and eats a lot of fruits and vegetables. She's found that she is really tired since changing her diet. What can she add to her diet to add energy but maintain the comfortable weight that she is at. ~ In my response, I mention lab testing with WellnessFX. Audio Question from Mike: Has a problem with his left shoulder. He's working out 3-5 times a week, doing intervals and weights. Lifting moderately heavy. Had a partial rotator cuff tear a few years ago. Rested it for 3 weeks and it healed up. Now every day that he lifts he gets pain the next day. What can he do to help with that? ~ In my response, I recommend this free report on Muscle Imbalances Revealed. I also mention the 7 minute Rotator Cuff Solution. Erin asks: Going for a run of 20 minutes or more often causes me to develop an aura migraine. Initially I get the bright spots in my eyes and if I continue running it will progress into the full-blown migraine. It only ever happens when I run in the morning and is made substantially worse when the weather is hot. Interestingly, I do a lot of other indoor sports and this doesn't happen during those training sessions, regardless of intensity. Can you suggest why this might be happening and what I can do to avoid it? ~ In my response to Erin, I reference my How to Get Rid of Migraine Headaches podcast with Ted Morter. Longbow asks: You mentioned in one of the earlier podcasts that recent research showed lifting lighter weights with more reps has the same result as the heavier weight with fewer reps. If the benefit is the same and the goal is "lift to failure", wouldn't it be better to lift lighter weights so the chance of getting injured is smaller? ~ In my response to Longbow, I mention this podcast that I did with Art De Vany. Also this podcast with Cary Nosler. Craig asks: I've heard a couple of things about "block training" (emphasizing one triathlon discipline at a time). What is your opinion on this? Dan asks: I was wondering what you thought about pedal spacers to widen the "Q-Factor". Is there a way to figure out what is the right pedal width for your body (besides getting a custom-fit)? Does hip-width have some correlation to foot-width? Jill asks: My monthly cycle can bring on some extreme fatigue with me unable to wake up to an alarm to exercise. It can be extremely frustrating and cuts down on the time I have to put in long sessions on the bike. As my exercise time drops off during this week every month, I feel I lose fitness and it seems to take a week or two to get back into a good groove, and then it happens again! Do you have any suggestions of herbs, supplements, etc that I could use to combat this fatigue? Is going on birth control pills the best option? ~ In my response to Jill, I mention Katylynn Wlesch's 21K Trail Run. I also mention my recommendations for estrogen dominance.

This makes it much easier to find the section you are interested in. ----------------------------------------------------- Listener Q&A: As compiled and read by Brock, the Ben Greenfield Fitness Podcast "sidekick". Audio Question from Ange: Could you weight in on "Carb Backloading"? Involves: Training in the morning when you get up, maybe have a cup of coffee (with cream) but have no macro-nutrients before working out. She always thought you should take in carbs and/or protein before working out. ~ In my response, I mention my original response to a carb backloading question. Audio Question from Matt: Planning on running some marathons and an Ironman in the next 12-16 months. Has a very irregular work/sleep schedule. Trains in the morning whether he work days or nights. He's looking for nutritional advice to fit a schedule like his. Also would like to know what to eat after his workout when he goes to bed directly after. What supplements should he take to make the most of his sleep - currently takes melatonin and casine-isolate shake. ~ I mention my sleep recommendations. Audio Question from "Belly": 2 years ago he was 30kg heavier than he is today (he is 33). Back then, he started walking several times a week and then started running. Loves running. Even though he has lost weight he still has a layer of fat around his belly. Could you elaborate on how to get rid of the belly fat (he knows about runner's belly related to cortisol levels). Audio Question from "Bones": His wife just had a bone density scan and was diagnose with osteopenia. They are wondering what supplements she should take. ~ In my response, I mention Capraflex. Also liquid trace minerals, Vitamin D, Magnesium, and Vitamin K2. Audio Question from Craig: Based on your recommendation he has been wearing blue blockers in the evening. Wants to know if there would be any advantage to wearing sunglasses in the morning before sunrise. Audio Question from Scott: 2 weeks ago he had blood work that showed his testosterone was low (8.2 nmol/litre 22.5 pmol/litre Testosterone Free Reading). Started taking medications. Has been running twice a week and as well as lifting weights. Had blood work done again and his testosterone levels went down. What would you recommend to raise his testosterone level? ~ In my response, I suggest that he read these testosterone recommendations. Audio Question from Pat: Not an endurance athlete, lift weights and does jujitsu. He recently read the book "Chi Running" and has started running once a week, just a couple mines (or 3 at most). He's never heard us mention the book and wanted to know what we thought. ~ In my response to Pat, I mention this interview with Danny Abshire from Newton Running shoes. I also mention this Chi Running audio cue I made. Christine asks: I am thoroughly enjoying your new book! I have discovered I am a mesomorph female and had a question about the workouts. Quite a few exercises require cable workout equipment, which I do not have in my home. Can I substitute alternative exercises that work the same muscle group and maintain the high rep, low weight protocol? ~ In my response to Christine, I mention the Body by Jake Tower. Elizabeth says: Last summer, as I was in training for my first half marathon, I decided to stop taking my birth control because I didn't want the extra hormones and all that goes with taking birth control. I expected to not have a regular menstrual cycle at first but from August to February I had only one period. I have gone to the doctor and she said it was because I am too lean and am training too hard for the marathon. She gave me progesterone pills to take to see if she could restart my menstrual cycle and it did but now it has been 2 months since then and I have not had another period. My body fat percentage is around 21%. I'm wondering what I can do so that I can have regular menstrual cycle and still train for endurance running events. Connie says:I had some cardiovascular test done but have no clue what the results mean and thought maybe you would know. I have done 4 Ironman races. I am very slow and had a gastric bypass 6 years ago. The Doctors are saying I tested extremely high so that's why I'm confused. I had a Bruce Protocol Stress Test and I lasted 17 minutes 7 seconds ending at 5.5 mph at 20% grade, my VO2max calculates at 71.07 using the formula of 4.38xT-3.9 (T=time I lasted on treadmill during stress test) My functional aerobic capacity attained was 160% and my SBPxHR is 27360. HR went from 61 to 171. Does any of this make sense because I am totally lost. If my stats are good does that mean I should maybe start to push myself to not be so slow.

Ben's Superhuman Performance Encoder wristband and Entrainer Drops - are now available. ----------------------------------------------------- Listener Q&A: As compiled and read by Brock, the Ben Greenfield Fitness Podcast "sidekick". Audio Question from Catherine: For several years she has had trouble with her shoulder. She has pain radiating through her neck, head and even sinuses. She does a lot of yoga, and the more yoga and pushups she does, the worse it gets. She had a snowboard crash that may have caused the problem in the first place. ~ In my response to Catherine, I recommend Muscle Imbalances Revealed and this free 40 page report. I also mention Dr. Herb Akers. Audio Question from Ryan: He's recently been experiencing some shoulder pain while swimming and is looking for exercises or stretches to help with shoulder pain. Audio Question from Joe: He has tons of "tech" clothing for running, biking, etc., but they all have drastically different Washing instructions. What is a good general rule to follow? ~ In my response I mention Shutout Detergent. Audio Question from Kyle: He wants to know if it possible to build high quality lean muscle while on a low carb diet and and high fats - as well as doing Bikram hot yoga 4 to 7 times per week? He lifts heavy weights (hard) but also loves the yoga. He's heard that yoga is good for him but that he will never build the size he wants while doing yoga. Audio Question from Low Carb Guy: Trying to get his head around running low carb while doing trail ultra marathons. If ketosis is binary why would an elite athlete fuel with gels at all? Is it possible to be in ketosis but do a quick exit to fuel with carbs? Does eating even a small amount of carbs mean that he won't be oxidizing fats? ~ In my response I mention this podcast Is It Possible To Be Extremely Active and Eat A Low Carbohydrate Diet? Marco says: Wondering what your thoughts are on Guarana? Andrew asks: I'm going on a 5 day hillwalking trip on the West Highland Way in Scotland carrying approx 14kg in my pack for 20 miles/day. What would you suggest is the best strategy for the three main areas I'm concerned about which are: energy, recovery and injury prevention (if possible)? Also, added to this I want to keep it lightweight as much as possible but most camping foods that are available are freeze dried and probably not the best in terms of quality. ~ In my response to Andrew I mention podcast 190 and also episode 199. Craig asks: There were a few items toward the avoid side of the Superhuman Food Pyramid that I found a little surprising; grapes, squash and strawberries. I believe the grapes may be on that end for their sugar content? The squash and strawberries are more of a mystery. Please enlighten me. Joe asks:My 13 year old son has begun running. I've always known something was wrong with his running, and I thought it was his ankles. As he passed me on a run the other day (he did 2.4 miles in 20 minutes!) I noticed his knees were close together and his feet kicking out in a diagonal manner. I did some research and I believe he is knock kneed. It isn't that obvious when he walks or stands. He walks with a minor pigeon toe. He is definitely not overweight. What can we do to correct this short of surgery?

Audio Question from Keith: Wants to know Ben's opinion on Tailwind Endurance Fuel. ~ In my response I mention Osmo Nutrition. Eve asks: I am a typically pear shaped female. I have done strength training diligently for several years, and I have trained for triathlon for almost a year. My upper body strength is really holding me back on the swim. I train swimming 3 times per week. I have worked with swim coaches and have followed numerous strength training protocols with several personal trainers. I bought your book "strength training for triathletes" and followed some of the exercises. I've had improvements in my leg strength, but not in my lats and arms. I eat Paleo with loads of fruit, plenty of protein, litre of milk per day with zero junk and zero gluten. Is there no hope for me? Even my mother can bench more than me :-( ~ In my response to Eve, I mention the SwimSmooth book. Rob asks: I was listening to you and Brock talk about gels and goos today, recommendations for half-marathoning. I started running hardcore last year and I found the half-marathon distance really tough until I started wearing a CamelBak and I was thinking about carrying honey packets with me as a natural source of energy, as opposed to gels and goos. I'm a budget runner as much as possible because I'm a budget sort of wage-earner and I can just grab these honey packets at the local coffeehouse. What do you think about using honey as an energy source during a long-distance run? KaLonny asks: Is there any validity to hair analysis? A local chiropractor offers this test to measure mineral content of your hair and, according to this particular website, "if a particumineral deficiency or toxicity exists in the hair, it usually indicates a mineral deficiency or toxicity within the body. This in turn, provides a great window into the metabolic activity within the body, which allows us to prescribe a unique treatment protocol in order to properly treat your condition. " I am interested for myself, but also for my daughter, who shows characteristics of autism and other behaviour issues. Is it legit or a waste of money? ~ In my response to KaLonny, I recommend these two tests: www.evitalhealth.com/Red_Blood_Cell_Elements.html www.spectracell.com/mnt/#nutrients Hope says: I'm 53 years old and have been going through the side effects of peri-menopause and menopause for many years now. I decided when I was in my later 40's that I would try to "run through menopause". I'm now running about 3 - 4 miles a few times a week and also do different types of cross training. I have completed a 5k and a 10k, but I find that I get too exhausted to put in any real extended mileage. I wanted your input regarding how to deal with the exhaustion, hot flashes and creeping weight gain which has been occurring. I have tried black cohosh and other remedies to no avail. My diet is overall very good - lots of veggies, clean foods, protein and not huge amounts of carbs, except for a treat. My mother had breast cancer twice, so there is no way I'll be touching any hormones. I am trying my best to keep fit and young, but I gotta tell you, it's been tough! ~ In my response to Hope, I recommend listening to my podcast on why women gain weight as they get older and taking a look at the Ben Recommends page. Nadine asks: I am an ex-triathlete who stopped swimming because of a problem with chlorine. Here is what the symptoms are like: after two or three swims in a week, I stop being able to digest fat, get heart palpitations (which I never get otherwise) and generally feel terrible. It took me a long time to figure out what the trigger is until my naturopath did some reflex testing with pool water and figured out that the chlorine in the water goofs up my liver and gall bladder. I stopped swimming in 2005. I do a lot of endurance training but really really want to get back into triathlon. I am going to try a lower chlorine pool in Vancouver but wondered if a) you have encountered this sort of reaction before and b) if you have any ideas about helping out with the chlorine. I have no respiratory symptoms. Shannon asks: I currently have a small tear in my labrum in my left hip. I have an acetabular impingement that seems to be why this has happened. I was a runner and practised a lot of yoga. I have been seeing a yoga therapist and doing physical therapy and my hip has been feeling better. I am not planning on having surgery, because my hip is feeling better. Do you have any suggestions or opinions about workouts? I would love to get back to running, but high impact activities make me nervous. ~ Heal Your Hips book.

Andy wrote: I recently "fell" into the sport of road cycling after trying it out last year during a vacation. I have always been active (4th degree Black Belt in Karate) though I now have to work within my sciatica that at times does not allow me to walk without pain. Riding does give me a minor back soreness but it does not hurt me at all! Even though I am now 56 I would like to get into this sport more seriously but with caution. I still have a full time job and yes a growing family thus I have to balance. So, where does one begin to establish a serious, though reasonable overall program that someone like me can use to challenge himself? ~ In my response to Andy, I recommend www.TriathlonDominator.com and www.Tri-Ripped.com Paul asks: I am a 63 yr old 30 + yr. runner. I have flat feet and hammer toes. The last few years I have had nerve pain under second toe on my right foot. I have used a metatarsal pad under toes with relative success. Lately pain hangs on after long runs. I went to a podiatrist and got a cortisone shot for the inflammation and was told I need an orthotic. I've seen insoles with a pad directly behind the ball of the foot designed to take the pressure off the metatarsal bone and would be interested in your view of the best way to approach this problem. ~ In my response to Paul I talk about the How To Run Barefoot post.
