Creatine, Protein + Supplements

Filed under: bodybuilding, Nutrition + Diet — admin @ 8:00 am

 People have asked me about supplements.  First, a caveat, I’m not a nutritionist, so ultimately you should consult one, or your doctor, for proper recommendations.

Second, let me throw my bias on the table.  I prefer to avoid the chemicals and supplements if at all possible.  My take is that ultimately good nutrition, and a balanced diet are in the end the best ways to achieve your training goals.

Creatine is a hot supplement among fitness folks.  I confess to having little experience with it personally, so I’ll just quote from ACE (American Council on Exercise):

“Several studies suggest that ingestion of 20 to 25 grams of creatine monohydrate per day for five to six days improves muscular performance during activities that require short periods of high-intensity poer and strength…”

They also note however some possible side effects like liver + kidney damage if you consume a lot, stomach cramps + diarrhea, and weight gain.  They specifically don’t recommend it for those doing endurance exercises as the weight would hurt your overall performance.

And on to the Protein question.  Protein, protein, protein.  Everyone’s obsessed with it, yet we only need 12% of our diet as protein.  And there are all sorts of plant + carb combinations that make a good protein for us.  So why all the worry.  Well you can read Michael Pollan’s book, or just go by his simplified motto: “eat food, mostly plants, not too much”.  What he’s distilling into this little sound bite is the fact that many of the diseases we face are caused by not doing one of those.  Instead of food, eating processed food.  Instead of mostly plants we eat sugary stuff, and too much protein.  And instead of not too much, we eat much too much.  That’s not to say that we should eat a little more protein if we’re training, ACE recommends increasing that 12% to 18%.

But vis-a-vis the protein supplements, be aware that too much protein can be a problem.

“Consuming too much protein can be physically harmful.  Extra protein must be broken down metabolically, and the waste products must be excreted from the body, placing additional strain on the kidneys.”

“Protein consumption in and of itself does not increase muscle size.  After the growth years, muscles must be stimulated by progressive resistance exercise to increase their size and strength.  In fact, even though American adults ingest plenty of protein, they lose more than one-half pound of muscle every year unless they perform regular strength training”.

Do some reading folks, there are a lot of myths out there…

reps versus power

Filed under: howto, bodybuilding, bodyweight — admin @ 8:00 am

There are a lot of milestones that I’m shooting for. One in particular is the one-arm pullup. This is not where one arm pulls on the wrist while the other arm pulls up. This is a real one-arm-only pullup where the other arm is not contributing at all. I ran into a rock climbing friend of mine who said that only 1 in 100,000 people can do this feat. I figure that makes it a good goal to strive for!

When you’re doing strength training, you want to be able to do comparisons so you can measure your improvement, and also see how far you have still to go. One great way to do this is by comparing reps to maximum total strength or power. Here’s the breakdown:

# of reps % 1 rep max

1 100

2 95

3 93

4 90

5 87

6 85

7 83

8 80

9 77

10 75

11 70

12 67

15 65

Ok, now how do we put this to work on the one-arm pullup? Here’s what I did.

Throw a rope over the bar and attach weight to it. The non-working arm pulls on the rope, and the other arm pulls on the bar. Keep adding more weight, until you can do your one-arm pullup. I weigh 150 pounds, and can do the pullup with 10 pounds attached to the rope, so my 1 rep max for one arm is 140 pounds. For working this skill, let’s put 15 pounds on the rope. Calculating that out, you’ll find that 135 pounds is 90% of 150 pounds. Looking up in our table above that means that with the 15 pound weight, I want to be able to do FOUR REPS.

This type of comparison of reps to total power can be used all the time in your strength training. If you know the total 1 rep max that is your goal, you can design reps at smaller weights to get there over time.

This technique provides you with another tool to apply during your training, allowing you to breakdown your goal into manageable and measurable steps.
