Making the most of your time in the gym

Many people follow the same exercise program week-to-week. This is a mistake. The body needs a challenge. That's why exercise progressions are necessary to improve our fitness. In this article we'll explore the many ways we can progress our exercise programs.

All About Sleep

How can ZZ affect your BF? (And your GH, TSH, IR, GT, and T2D?)

The safe carbs:

A recent workshop taught me that people are quite confused when it comes to whole grain, unprocessed carbs. They just don't know what they are, where to find them, and what they're good for. Check out this article for a great treatment of whole grains.

Research Review: Front or back squats

May the force be with you... but hopefully not on your kneecaps. Which squat squashes knee cartilage less? Front or back? Biomechanics has the answer! And you thought physics was boring.

All About Creatine

Creatine's a selfless type. It really wants you to finish that sprint or squat set, so it hands out its phosphates all over the place. It's also a meat-and-potatoes supplement, literally and metaphorically. It's in your steak, and it's been fuelling athletes and bodybuilders safely for decades. Find out how creatine does its Mother Teresa routine, and why it's a good addition to your supplementation regime.

Informal Experiments: We’ve found the perfect warm-up! (Well, maybe)

"Conan! What is best in life? Also, what is the best warm-up for the bench press!?" "To crush your personal records, to see the barbell driven before you, and to hear the lamentation of the 98-lb weaklings! And probably dynamic stretching."

Research Review: Is Splenda safe?

What if, as Nina Simone sang, you want a little sugar in your bowl, or a little sweetness down in your soul? Well, you might opt for Splenda. But are there health consequences to consuming sucralose? Here's what one study suggests.

All About Soy

From thyroid disease to GMOs, from breast cancer to infant formula, there's been a lot of conflicting media reports on the safety of soy. We review the evidence, and explain the source of soy's power as potential hero or villain.

The Super Shake Guide:

Store bought and smoothie shop nutrition shakes are usually heavily sweetened, loaded with poor protein sources and are missing many nutrients found in whole foods. The Super Shake, on the other hand, is packed with all kinds of good stuff like high-quality protein, fiber, good fats, antioxidants and more.

Cardiovascular Disease:

Poor nutrition can be a heart breaker, a love taker, and definitely not a dream maker, so don't you mess around with CVD. (Apologies to Pat Benatar.)

To count or not to count: JB & Ryan talk calories

On the web, there's a lot of interesting debate going on right now about the relative value of calorie counting vs. intuitive eating. Which is better? Come listen to this interview to find out.

Athlete Profile: Peggy Rainbow – Update

For PN Lean Eating alumnus Peggy Rainbow, January 2009 roared in like a lion, but March went out like a lamb. A ripped, happy, trophy-holding lamb, that is.

All About Flax

Flax, one of humanity's oldest cultivated crops, offers several potential health benefits, particularly because of its fibre and omega-3 fatty acid content. Yet in many cases, the data are mixed; we're still not completely sure which health conditions flax definitively prevents or treats. (You might say: Flax on? Flax off?)

Expert Tip: Make it simple

What should your carbohydrate to protein ratio be in your postworkout drink? Should you eat carrots before or after exercise (and should they be cooked so you absorb the beta-carotenes or raw so you get their natural carroty goodness)? Should you avoid eating after 6 pm... or was that 8 pm? Ack! Relax. It doesn't have to be that complicated.

Athlete Profile: Howie Clark

You hit the gym 4 hours a week. Great! But what do you do for the other 164 hours? A good workout plan only accounts for about 2-3% of your time. As baseball player Howie Clark discovered, it's dedication and commitment OFF the field -- including good nutrition -- that really counts.

All About Dehydration

Feeling thirsty? Maybe it was that soy-sauce-laden takeout. Maybe it was the four beers after the game with friends. Or maybe it was that jog in Death Valley. In any case, you'd better drink up -- because dehydration can put a cramp in your athletic performance.

Strategies for getting control of stress

Purposeful rest and recovery. It's an important part of the fitness equation. Yet it's the one most of us neglect. If you don't build in 30 min of parasympathetic activity per day, you need to come check out this article. It'll show you how to build in restful, parasympathetic activities in order to help keep stress in its place.

Athlete Profile: Shawn Haviland

Pre-game plates of pasta and pitchers of sweetness, that's not the diet that leads to eliteness. Shawn likes the mojo that eating well brings, now he finds mushrooms his favourite things. (Apologies to Julie Andrews.)

All About Diet Sodas

Diet soda is a no brainer. We drink it to avoid the sugar calories from regular soda, right? But do the benefits of consuming fewer sugar calories outweigh the risks of consuming artificial ingredients?

Expert Tips: The cone of learning

Revealed: JB's magic secret for making nutrition and exercise knowledge stick to your brain like a barnacle!

A women’s guide to body transformation

Here's a figure program that's designed for results -- whether you want to compete as a figure athlete, or just look and feel like one.

Athlete Profile: Emily Zelinka

Transforming one's physique to be stage-ready is a challenging task. The training and nutritional diligence is arduous enough, but this transformation also challenges our self-esteem and the way we see our bodies' natural flaws and unique features.

Fructose vs glucose: What’s worse?

Hey, Kool-Aid! What's going to make us fatter and sicker: fructose or glucose? Oh yeaaahh!

Diabetes types 1 and 2:

What if we told you that there was a disease that struck 7% of the US population (and nearly one-third of people in some areas)... a disease that led to a multitude of other common and serious diseases, disabilities, and premature deaths... and that about 85% of these disease cases were completely preventable? Read all about diabetes mellitus, and what YOU can do to cut your risk, right now.
