Strength Training Principles and Guidelines: Part Two
Almost any form of exercise will stimulate strength and muscle development. Unfortunately, misconceptions, myths, and misunderstandings plague the fitness industry, especially regarding strength training. There is a huge attrition rate among those starting a strength training program primarily because most people are not taught the principles essential for a safe and effective program.
This article is part two of a five-part series discussing the fundamental principles and guidelines of a safe and effective strength training program. It discusses the importance of forcing blood to your muscles and proper lifting speed. The previous article, part one of this five-part series, explained the correct warming, stretching, and cooling methods for a safe and effective strength training program. The following exercise guidelines are essential for your safety and the effectiveness of your strength training program.
Importance of Blood Supply to Your Muscles
Understanding the value and purpose of targeting or forcing blood to the muscles you are training is essential. Many of the principles we teach have the sole purpose of forcing blood into your muscles. When you use proper lifting technique, you will notice blood rushing to the specific muscle you are training. And this is precisely what you want to happen.
When blood is forced into your muscles during your weightlifting program, it potentiates the "microtrauma" or tiny muscle tears we mentioned earlier. When this happens, your muscle tissues repair and rebuild themselves bigger and stronger than they were--if you allow ample resting time. This is why you never train the same muscle group two days in a row; if you do, you cut off the rebuilding process.
You will know you are using proper form when you feel warmth, fatigue, and a "burning" end of each set for each muscle group. If you do not get this feeling at the end, you should review the proper form for your exercise. This may be an indication that you are making other common mistakes in your routine that do not allow blood to be fully targeted to your muscles.
One of the most common mistakes is not training their muscle groups in an organized, systematic fashion. Always do every set and every exercise for specific muscle groups together. For example, if your chest routine consists of three sets of bench press, do all three sets, separated by resting periods, and then go on to the next muscle group. Or, if your chest routine consists of two or three different chest exercises, do all of those chest exercises together. Do the bench press, then the Incline bench press, and then the flyes, for example, until your chest routine is complete. Then you can move on to the next muscle group.
Many people make the mistake of doing a set of Bench Press for their chest, then a set of Biceps Curls, then another set of Bench Press, and then on to another muscle group, and so on. This does not fully target blood into any one muscle group. You are just teasing your chest muscles and then moving on to tease another muscle group without ever targeting enough blood into any muscle group to cause much stimulation for improvement.
Another common mistake is eating right before or too soon after your training program. Eating just before or too soon after your workout will not allow you to get enough blood into the muscles you are training, causing your heart and digestive system to work too hard and compromising the oxygen and nutrient delivery to the working muscles.
Think about this: Digestion takes a lot of blood to work effectively. The more blood your body sends to digest your food, the less blood is available to go to your muscles, to rebuild and increase strength. You should wait at least 60 minutes after eating before you start your exercise program.
In the same way, please don't eat too soon after ending your workout because you want the blood you just targeted into each specific muscle to remain there as long as possible. If you eat food too soon after your workout, the blood will be forced out of your muscles and into your digestive system. So wait at least 60 minutes after your program before you eat a meal.
Of course, you should not go to your workouts hungry; you want your system for performance enhancement and energy. However, try to eat an hour or more before workouts, nutrients in your body, and ensure your meal includes foods rich in complex carbohydrates and protein and low in fat, sugar, and cholesterol.
Lifting Speed
Lifting speed is one of the most important elements in weightlifting. It has a significant effect on how much blood is targeted to your muscles. Speed plays a significant role in the incidence of injury, as well as strength and muscle development. Fast lifting creates momentum and doesn't promote blood flow to the muscle. Slow movement creates less momentum and less internal muscle friction. Slow lifting requires a more even application of muscle power throughout the movement range and promotes rapid blood flow into the specific muscle you are training.
In every strength training exercise for every muscle, there are two different parts to each repetition of the exercise set performed. One, the concentric contraction--called the "positive" phase of the repetition--is the part where the muscle is doing the work, such as the lifting motion of the bicep curl--from the beginning where your arms are hanging straight down to the point where the weight is lifted. The second part is the eccentric contraction- called the "negative" phase of the repetition- which is the part with resistance because you are returning the weight from the end of the positive phase back to the beginning. In the bicep curl, you let the weight return slowly to the beginning position, with your arms extended straight down again.
Letting the weight return slowly in the "negative" phase is more critical than in the "positive" phase. Coming back slowly with resistance on every exercise is very important because this is the phase that promotes blood flow to your muscles and thus causes microtrauma, building your muscles even stronger during your day of rest. We recommend one to two seconds for each lifting movement (the positive phase), and three to four seconds for each lowering movement (the negative phase). Whatever your actual lifting speed, remember to always come back slower with resistance (the negative phase) for every weightlifting exercise. If you find the weight so heavy that you cannot come back wholly and slowly control the movement, you should lighten the weight until you can. Many people pay far too much attention to the lift's quantity or weight and not the movement's quality. Your muscles cannot know how much weight is on the bar or machine, but they will respond very well when using good, controlled form and come back slowly with resistance.
Please check back for Part three, where I'll discuss the importance of proper lifting technique, exercising through the full range of motion, proper exercise sequence, and the correct number of sets for what you're trying to achieve. Until then, remember to use slow lifting speeds and try to get as much blood into the specific muscle you are training as possible. Good luck, and enjoy all the incredible benefits of strength training.
