A multi-set involving the training of two opposing muscle groups back to back is called what?

Antagonistic training is a training method that involves working two opposing muscle groups in a back-to-back fashion. This approach capitalizes on the physiological principle that while one muscle group is being worked, the opposing muscle group can recover. For example, performing a set of bicep curls (which targets the biceps) immediately followed by a set of tricep extensions (which targets the triceps) exemplifies this strategy.

This technique not only enhances efficiency in workouts by reducing overall rest time needed between sets but also helps to maintain a balanced development of opposing muscle groups, thereby potentially reducing the risk of injury and muscular imbalances.

The other options mentioned do not accurately describe this technique: maximal workload typically refers to the maximum amount of weight or effort that can be handled, stacking does not pertain specifically to muscle group training, and aerobic activity refers to cardiovascular exercises rather than strength training practices like antagonistic training.
