Option d; You can perform the same exercise five times in a row without risking injury if you give yourself enough time to recover between sessions that target different muscle groups.
Contractile tissue that is organized into coordinated systems is muscle. By outward appearance and cell location, human muscular systems are categorized. Smooth, cardiac, and striated muscles make up the three different types of muscles (or nonstriated). The majority of the body's muscle tissue is made up of striated muscle, which is virtually solely connected to the skeleton. The somatic nervous system regulates the multinucleated fibers, which provide movement by applying pulls and lever-like forces to the skeleton. The sinoatrial node, the heart's pacemaker, controls the cardiac muscle's rhythmic contraction. Despite being a specialist striated muscle with several centrally positioned nuclei in elongated cells, cardiac muscle is not controlled voluntarily.
