And if you’re serious about your career as a trainer, or you want to get the best results in your own workouts…
• You need to understand the physics of resistance exercise, which allows you to do only the best exercises, and do them correctly.
• You need to know how to which exercises allow optimal muscular development, and which exercises allow you to lift the most amount of weight (these two are very different objectives).
• You need to know how to explain to your clients why certain exercises are better than other exercises, and an exercise is more beneficial performed one way, instead of another way.
This should be important to you, even if you only want optimal results for yourself.
But if you are in the business of “teaching” resistance exercise, it is IRRESPONSIBLE for you to not understand biomechanics, as it relates to resistance exercise.
