When looking for exercise equipment there are certain guidelines to follow. Here are the issues to consider: 1. Effective - In order for a piece of exercise equipment to be effective it needs to be able to challenge all of the muscle groups in the body. This can only be done with multiple levels of resistance (tension). The fact is that each of your muscle groups is a different size and a different strength. Your thighs are stronger than your arms‚ your back is stronger than your shoulders etc…

main muscle groups of the body and their function There are three main categories that the muscles in the human body fall into: • Skeletal Muscle Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner‚ for example‚ if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill. In this case

What is a muscle twitch? A muscle twitch is the fasciculation ‚ or "muscle twitch"‚ is a small‚ local‚ involuntary muscle contraction and relaxation visible under the skin. B. According to the graphs‚ which muscle has the fastest twitch? Why? The lateral rectus eye muscle has the fastest twitch. It
