Final answer:
Supersetting is the practice of performing two exercises for opposing muscle groups back-to-back with minimal rest. This is an effective form of anaerobic exercise that can lead to increased muscle and bone mass as fast-twitch muscle fibers are engaged.
Step-by-step explanation:
The combination of sets of two exercises targeting opposing muscle groups completed in succession with little to no rest between them is known as supersetting. This form of physical exercise involves alternating between exercises that target agonist and antagonist muscle groups -- for example, the biceps and triceps. By allowing one muscle group to work while the other rests, you can maintain a higher intensity of workout within a shorter period.
LibreTexts notes that muscles can only contract and therefore, to move bones in opposite directions, pairs of muscles must work in opposition. A common example of this is the biceps and triceps working to bend and extend the arm at the elbow. Another example includes the quadriceps and hamstrings for knee extension and flexion, respectively.
Anaerobic exercise, which includes activities such as sprinting and push-ups, involves short periods of vigorous muscular work. These exercises use fast-twitch muscle fibers that consume small amounts of oxygen but produce significant gains in muscle and bone mass and strength.
