food components that readily dissolved in water and often impart gummy or gel-like characteristics to foods. An example is pectin from fruit, which is used to thicken jellies. Indigestible by human enzymes but may be broken down to absorbable products by bacteria in the digestive tract.
A spin class is an exercise class in which a group of people ride on stationary bikes. A spin class typically has loud, energetic music playing while the class follows the instructions from the leader to add or subtract resistance to the bikes.
Primary Muscles. The main muscles used in a spinning class are the quadriceps. These are the large muscles on the front of your thighs. When the class begins an incline, the quadriceps is the muscle that will power you through the segment.It pushes down on the pedal and straightens your leg.upporting Muscles. The gluteus maximus and medius, the muscles in the backside, push forward on the pedal at the top of the stroke in a spinning class. Strengthening these muscles can help you improve your muscular endurance. Try some of the same exercises that strengthen the quadriceps, such as lunges and squats.
