I hear quite a bit about vitamins and minerals. Which ones are the most important?

Part I - Vitamins
Such a simple question, yet a fairly involved answer. To start I’ll share a little nutrition lingo with you, so at least you’ll sound a little like you know what’s up.
Difference Between Micronutrients and Macronutrients
Vitamins, minerals and other trace elements are all called micronutrients whereas carbohydrates, fats and proteins are [...]

A guy at my gym says you can grow just as much from lower weight, high-rep sets and higher weight, low rep sets. Heās crazy right?
by Dr. Chad Kerksick on Aug 22, 2010, under Customer Q & A, Muscle Science
Much of the basis of strength and conditioning and resistance training principles have centered upon using 70% to 80% of your one-repetition maximum for 10 to 12 reps with low rest to maximally stimulate hypertrophy (Fry 2004; ACSM 2009). This what is taught in every exercise science curriculum across the country, by strength coaches across [...]

I have always been into lifting and my girlfriend has been on me to run a half marathon. As you can imagine, from a life of lifting Iām not exactly swift like a deer if you know what I mean. What would be the best way to go about getting my wind and legs under me?
by Dr. Chad Kerksick on Aug 18, 2010, under Customer Q & A, Muscle Science
I can relate to this question. My years throughout college and after I rarely did any form of cardio exercise. I lifted weights several days a week and moved at a pretty fast clip when I was in the weight room, so I didnāt feel the need. More importantly, I just didnāt [...]

When I read about vitamins and minerals, I see reference to RDA, DRI, EAR, UL and AI. Which should I care about?
by Dr. Chad Kerksick on Aug 10, 2010, under Supplement Science
The Food and Nutrition Board along with the Institute of Medicine have worked together to provide reference tables for all micronutrients in our diet. What are micronutrients, you ask? Itās those nutrients that we need in our diet in small amounts, hence the name āmicroā. If you still have no idea what [...]

Itās hot out thereā¦Be smart and use common sense
by Dr. Chad Kerksick on Aug 05, 2010, under The Professor
With a background in athletic training, Iāve seen my fair share of heat injuries and problems and Iām amazed at how many times people (athletes or not) get into trouble with the heat. Our bodies produce heat and lots of it when we exercise and when the temperatures outside are high, it becomes nearly [...]

Muscle Physiology and Strength Research 101
by Dr. Chad Kerksick on Jul 27, 2010, under Muscle Science
If I would like to understand more about muscle and how exercise training effects it, what are the key things I should understand?
I guess you could call this Q/A a lecture titled āMuscle Physiology and Strength Research 101ā. I must warn you that you are flirting with dangerous territory asking a muscle geek to [...]

I just got back into training, and Iām amazed (No Depressed) at how sore I am. And I didnāt even think I was lifting that heavy! What happened and what can I do to prevent it?
by Dr. Chad Kerksick on Jul 21, 2010, under Customer Q & A, Muscle Science
Congrats for getting back into it. This is really a common occurrence, and unfortunately not a very clear cut answer. Studies have shown that strength is able to be sustained for quite some time after not training (1), but growth and endurance are lost more quickly. Unfortunately, I donāt have many magical things to say. [...]

Which Amino Acids are the Most Important to Consume?
by Dr. Chad Kerksick on Jun 21, 2010, under Supplement Science
This is a fairly straightforward answer now, thanks to decades of research and likely millions of dollars in research money. Before I dive into it, though, Iām going to provide a little additional background over amino acids and proteins as a whole. Amino acids are for the most part the bricks that when added together [...]

Concentrate, Isolate, Hydrolysateā¦Whatās the Difference?
by Dr. Chad Kerksick on Jun 13, 2010, under Supplement Science
This certainly is a relevant question and one that all of us at some point or another would have liked to have known a little more information about. I know when I first started looking at protein supplements; I was blown away by all of the different types of protein that was available. [...]

Focus On the Big Picture
by Dr. Chad Kerksick on Jun 09, 2010, under Supplement Science
My mom always told me that if you worry about the pennies the dollars will take care of themselves. This saying is true for financial conversations as well as exercise and nutrition. Iām amazed at how conversations related to exercise and nutrition are often dominated by details. When I try bringing the [...]
