Listener Q&A:

As compiled, deciphered, edited and sometimes read by Brock Skywalker Armstrong, the Podcast Sidekick and Audio Ninja.

Can Marijuana Damage Your Brain and Liver?

Mr. Mary Jane says: Ben, you've been talking about marijuana a lot lately and he was reading a book on ayurvedic medicine which mentioned how marijuana “is toxic to the liver and brain cells, however if one smokes a pinch of calamus root powder with marijuana this herb with neutralize the toxic effects of the drug”. What do you think? Does this have any merit?

In my response, I recommend:
NatureCBD
Article: The Effects of Weed On Exercise

The Best Way To Train For MMA Fitness

Richard says: He is a boxing and MMA coach, and is wondering if you consider fight sports to be endurance events. Both only go for a few minutes (no where near an Ironman) but training can be long grinding days, plus you also have to take punches and control your emotions. What do you think is the best way to train fighters? The same way you would train for triathlon? They need long grinding workouts with repetition but they also need the explosive power.

In my response, I recommend:
Martin Rooney's Workout Books

Should You Avoid Iodine?

Rob says: He's just sitting down to eat some post workout corn-on-the-cob and noticed that his sea salt does not contain iodine. This made him wonder how much iodine a person actually needs on a daily basis, why, and where are the best places to get iodine… since it's not in his sea salt.

In my response, I recommend:
Aztec Sea Salt
Thorne Multivitamin

Benefits Of Fasted Workouts

Erica says: In the morning she usually wakes up at 7:00, has a green smoothie at 9:00 and works out at 10:30. Do you think it would benefit her to switch the order of the workout and the smoothie so she is working out fasted and fueling afterwards? What would be the benefit or drawback?

    Hi Ben,

    I listened to this specific podcast on my way back from a Spartan Sprint last year. (Sacaramento, 2015)

    It came to mind again because of podcast #354 wherein you had mentioned the idea that taking protein immediately after a workout may not be optimail; it’s likened to cold water immersion blunting the anabolic signaling of muscles after strength training.

    May I please ask for clarification?

    Are you an advocate of cold water immersion after exercise – including strength training?

    Did you find the 2015 studies flawed? Are strength and adaptation mitigated or entirely blunted with cold water immersion after exercise?

    Are contrast showers the same as cold water immersion? I’ve been using this recovery method after my workouts and it does seem to help with the rate with which I heal, but I’m a little worried I may be adversely affected the adaptations that go along with strength training.

    (I’d be more likely to trust your recommendation since I believe you have a more holistic understanding of the human body and exercise.)

    1. Big picture is WAIT to do the ice bath or ice shower until at least a couple hours after resistance training as it appears doing it acutely can indeed blunt training response.
