Answer 2

Depending on how you have your pedals, handle bars and seat set up, you are using a combination of your glutes, quads and hamstrings. There are also almost a dozen smaller muscles always involved with basic movement and balance. With the regime you're performing however, the muscles benefiting the most will be the muscles that pump your heart.
