Weights and plyos are needed for a complete training package.
I received an email from someone who was concerned that we were making claims that isometrics were better than weights and plyos and that these two training methods are not required.
I answered with the following, assuring him that we strongly encourage the use of all types of training routines, because they all have their place when it comes to improving sports performance.
1st - Yes, isometrics with the resistance band can help to maximize your speed. This does not mean that you will maximize your speed by only doing these exercises. What it means is that if have already gotten to the point where you are not seeing any more gains in your speed and you have not done isometrics with the resistance band, then you should see additional gains in your speed with these exercises - and, therefore, in this way maximizing your athletic speed.
2nd - I don’t believe that we have stated that weights and plyos are not required. I do believe we have stated that all around conditioning, including strength, endurance and coordination as well as speed are important to an athlete’s success. We do say that isometrics with resistance bands will outperform weights and plyos when it comes to developing muscle speed, but this does not imply that the other forms of training are not superior for developing other aspects of athletic performance.
3rd - I agree that we have not done a good enough job of making it clear that isometrics with the resistance band can and should be done in conjunction with other types of training, and that other types of training are also important in a complete training program. Though we do suggest that some types of training often produce disappointing results when it comes to developing speed.
4th - I can say that the testimonials have been submitted by legitimate users of the program, and they have given their permission to have their testimonial published.
I have since published a 4 part article that talks about the muscle contraction types, how different training routines use each of these contraction types, and how used together an athlete can put have a complete training program that delivers improved sports performance.
