For today’s edition of Dear Mark, we’ve got a four-parter. First up is a question about using the cable weights at the gym to build strength. Should they be discarded by the serious trainee in favor of exclusive barbell work, or do they offer something unique and worthwhile? Next, I discuss potential strategies for the reversal of arterial plaque. It’s not guaranteed, but there are some promising leads. After that, I give my take on stem cell meat. Am I opposed? Am I intrigued? Finally, I give my take on replacing your desk chair with a Swiss ball for a reader who can’t get a treadmill desk and wants the next best thing.
On September 11, 2001, passenger jets struck the Twin Towers, leveling them, killing thousands of New Yorkers, and traumatizing tens of thousands more. Among those directly affected, but not killed, by the attack were 1700 pregnant women. Some of those women developed post traumatic stress disorder, some did not. When the PTSD-positive group had their kids, their cortisol secretion was lower and stress response to novel stimuli was impaired. Although as fetuses they weren’t conscious of the chaos, it affected them as if they had directly witnessed the blast. The affected children were no different genetically – they didn’t have “the stress gene.” Rather, the activity of the genes that regulate the stress response had been altered by an environmental input.
This was epigenetics in action.
Simplicity is baked into the Primal Blueprint by design. You eat plants and animals, avoid grains, get plenty of sleep and sun, and spend time doing things you love with people you love, and things just kind of fall into place. You can tinker around the edges and get really into the details, but I try to make this stuff as simple as possible. I’ve especially tried to distill exercise, a notoriously contentious topic, down into a simple, “universal” recommendation – move frequently at a slow pace throughout the day, lift heavy things twice or thrice a week, and sprint once in a while. While I maintain such a regimen will get most people reasonably fit and let them recover easily from their workouts without having to think too hard about recovery, it’s not the same for everyone. Some folks, particularly my harder-charging readers, my CrossFitters, my endurance athletes, and my barbell fanatics could use a more detailed discussion on workout recovery (since, after all, recovery is everything).
Today, I’ll start that discussion with a focus on seven factors that can impair your workout recovery:
One of the most common questions I get from readers is the same one I get from people who have no idea who I am or what I do: “What’s your workout, dude?” Because I write a blog that discusses the latest fitness research, some of you might get the impression that I’m constantly switching up my routine to incorporate the latest and greatest. Many times, you assume that because I wrote approvingly about something, I must be doing that thing. Well, by and large, I am not doing that. Even if some particular lift is proven to build the most strength most efficiently, I mostly stick to my tried and true. I’m no longer an elite athlete. I don’t need the latest and greatest. If it works for me and my goals, I stick with it. Of course, it helps that the way I train was already fairly consistent with the latest research, and is easily fueled by my Primal Blueprint eating strategy.
Here’s one of the latest inquiries into my training:
It’s been awhile since I did a post on chronic cardio. I had a good string of them going several years ago, and I thought I’d done a good job explaining why I was so opposed to excessive endurance training. Despite my attempts to clarify, though, I still receive a lot of questions and comments about cardio. People just have a tough time divorcing themselves from the notion that cardio – as much as you can cram into your schedule – is the key to health and fitness. I don’t blame them, really. It’s conventional wisdom, after all, and it’s what I thought for years and years. Clearly, another post is needed.
Evidence against chronic cardio continues to mount, so there’s a lot to cover. But before we get to all the research, I have a few thoughts about the heart.
