Hi, Looking for expertise. Please help me find the right help that could transform lives by being the living example of health and physical strength and function restoration. I am looking for a program/ person/trainer/ professional physical therapist, physiotherapist, who could video shoot for a new you tube channel, if they chose, who to heal my body and injuries, imbalances, compensations, at 53? I use to be a body builder, au natural, for four years in my twenties. I want to be balanced, functional, stronger, and flexible in areas I have lost some. Please help. I soon will have some foot bones fused to fix my arch because the posterior tibialias tendon is torn and retracted. the one responsible for raising up on your toes. My right hip hurts now too probably from muscle compensation. I wish they could repair then tendon but he said he could not, that it would fail. Ive already had both shoulders rotator cuff tendons repaired in 2012 and 2013. and my subscapularus seems to be the tight one interfering in shoulder flexibility. it gets stuck, and I hear clicks or snapping when I do some of the PT exercises. I believe aging is not real as it comes to myself, its from not doing any thing and gaining imbalances and compensations when I stopped taking care of myself. and I use to drink. I stopped. I eat healthy, no processed food except if I process it myself. I have been losing weight because of stopping all alcohol and don't eat any conventional sweets or sugar. I want to show the world you can heal and gain strength. I can not do an olympic squat. not even one with my body weight. And not one push up and I can not do one pull up. not at all. I want to heal and become functional, and gain strength...endurance. to be able to play and lift my granddaughter again. please help. Any trainers or professionals wish to help me? We have a spiritual community space building ( The Octagon) that could be converted into a whole training and rehabilitation center. I am at shireinthewoods@outlook.com Tayha Anderson we have cabins for rent and our Octagon building which could be transformed into a whole healing and rehabilitation center. I just want to be an example for others without hope, and show and prove that you can heal and gain strength enough to function and live well. Especially to play again, run again and dance with my daughter. ride horses again. Please help or pass along this info to anyone who can or would be interested in helping me so we can help the world of those who are so depressed and limited physically. Please help me find the right help that could transform lives by being the living example of health and physical strength and function restoration.

Very interesting. For those of us in our 70’s and beyond who can see how being weak and ill drains our economy and resources, a discussion focusing on staying strong and flexible the last quarter of life would be very helpful. Identifying resources, pitfalls to avoid, and tips would all be very welcome. The last thing any of us want is to be a burden to our children, but we’d love to continue to be able to get up and down from the floor, chase grandchildren, hike trails, do hours of volunteer work lifting and loading food boxes at the food shelf…whatever life brings.

Dr. Galbin knowledge is mind blowing both in width and depth. On top of this, he has gathered a more than decade’s long DAILY with ELITE ATHLETES. The two thinks compounded are a unique snowball effect of first hand marginal knowledge applied while at the same time a pragmatic approach on how to granulate it for a specific one o one needs. The huge humus of that is a genuine humility, curiosity, clarity of thinking, execution, ground experience, passion, and inspiration. When he is speaking like in this podcast i am fascinated by his contagious passion and his ability to be clear, speak easy, and for the “folks”. Thanks Dr. Galbin. I think that this has been some of the most informative and interesting 2h’s ever. Thanks Dr. Attia for hosting Dr. Galbin, one of the best podcast.

Fun fact! I worked in a lab that was looking at multinucleated cotton cells due to meloidogyne nematode parasites. I cut those cells into something like 20nm slices, took TEM images and fed those images into a computer to generate a 3-d image of the cell. We found out that the cells were not syncytial at all and that the nucleus was actually lobed out and that prior descriptions had all been wrong. The lab published and everybody said, "oh wow. That's cool. Anyway, when is the entomology picnic?" And that was that.

On Isometrics, as a Calisthenics athlete I can say there are also other advantages: Pros: -Safety -Time under tension: much easier to maintain and reach true failure. -Challenge specific ROM: a) otherwise undertrained or b) sticking points. -Specificity: strength gains comes very fast with proper training. -Simplicity, which transfer in easier technique and more effective training. -Learning: Most of isometrics are also starting or ending point of a lift. (for example: hanging for a pull up, or Rings support with Dips). This translates in a better visualization of the lift, since you have a really well understanding of where to start and how to finish. -Variety of stimulus compared to standard training. This also helps to "take a break" during the week. Cons: -Not Hypertrofic as compounds movements -Not always functional as compounds movements -Not time effective as compounds movements -Specificity: No transfer on other angles/lift -Not always easy to measure or increase load. BEGINNER TRAINING EXAMPLE: In Calisthenics, most skills are isometries. Since are so specific, if it make sense to train them only if you have the specific skill as a goal. Otherwise there are always better alternatives (compound movements). Anyway, is always good to insert some isometrics for variety. Exercises: Legs A: Horse stance Legs B: Single-leg Reverse plank (belly to the ceiling) PULL A: Hanging (+L-sit) PULL B: Tuck Front Lever PUSH A: Handstand PUSH B: Ring Support (+L-Sit)

I agree. While I feel Peter Attia is brilliant and really knows his stuff.... I, unfortunately, always seem to come away from listening to his interviews AND his AMA'S feeling that it's more important to him to prove how knowledgeable he is, than to try to break the discussion down into understandable bits of usable data the layperson can use to improve their health & fitness. I unsubscribed from Dr. Attia's monthly premium subscription - that I subscribed to for 6 months- for that very reason. Just wasn't able to glean helpful, usable information from being privy to his full AMA podcasts. 🙄

@antoniosdongas157 😆 haha, loved your analogy about the watch...🤣 (I have a son like that, btw🙄) I should try to correct myself on my attitude re Dr. Attia - while I trust his knowledge (ahem! Probably too much😳), I should refrain from accusing him of 'showing off his knowledge' by talking above the lay person's head - that's really not fair to him. I do think, though, that his often getting too scientifically technical for us lay people is just a phenomenon that 'happens'...especially when 2 very brilliant people get together and discuss a topic they love and are SO well versed in. I've watched Dr. Huberman (whom, of ALL the scientific types I follow)...has it down to a science how to include his mainly 'lay' audience in the convo so that we, also, can understand what these 2 brilliant minds are talking about. As result, I did feel that Andy's input in his Huberman interviews was totally understandable in the series of fitness interviews Huberman did with Andy. But...get TWO of these types together who, idk 🤷, maybe forget their lay audience so thoroughly, that they seem to completely let go of the reins and FAGET-ABOUD-IT!😳!... About a third of the way in, they've lost all but the most astute scientific types who might be listening 🙄

I would like to know the opinion of both of you related to taking amino acid tablets to help increase protein intake. I’m in my 50s and perimenopausal. I do eat healthy and work out. I find it hard to get the amount of protein I need due to the fact that I’m pescatarian and I’m a busy cardiac nurse. Our time at work to eat is very brief. So besides drinking protein shakes, do you find it helpful to take amino acid supplements?
