A bicycle machine is a piece of exercise equipment that replicates the movement of an outdoor bicycle and can be used for both cardiovascular and strength training. There are many different types of bikes, ranging from basic stationary models to high-tech bikes with computerized systems for tracking workouts. Choosing the best bike for your needs requires considering the space you have, your budget and workout goals. Developing muscle fatigue or an injury can limit your workouts or cause pain and discomfort.
The bike’s seat must be level to support your body weight and provide a comfortable pedaling position. If the seat is too high, it puts strain on your knees. If it’s too low, it may cause you to slide forward while riding and put pressure on your hands, arms and knees, which can lead to pain and injuries. The optimal seat height for a person is when the front leg has a slight bend at the bottom of the pedal stroke, with the knee nearing a 155-degree angle.
Bicycle wheels are made of a strong hub with a thin rim and several spokes, which help to make them both lightweight and strong. The spokes work to increase the bike’s strength and to reduce friction between the wheel and the axle that carries it. The taller the bicycle wheel, the more it can multiply your pedaling effort to create speed.
Cycling tones and strengthens the quadriceps muscles, which are the large muscles in your upper thighs that extend your knee. During the downward portion of the pedal stroke, the quadriceps contract to help straighten the knee and then flex or bend at the hip to propel your foot down towards the floor. The hamstrings, which are the larger muscles in your lower thigh, also get worked during cycling.
