2. The quadriceps femoris (four muscles in front of thigh) plays an important role in riding. Every time you go down the steps, they push your legs and knees strongly.
3. When your feet paddle through the lowest point of the circle to get exercise, the gluteus maximus (located in the buttocks) is involved.
4. When you bend your knees during the pedal stroke, you will use the muscles at the back of your calf (located at the back of your thigh). Moreover, in the process of drawing a circle with the pedal, every time you draw backwards and pull up after the lowest point, the muscles behind your legs can get the best training.
