Which fitness format emphasizes increasing muscular strength and endurance by using an opposing force for resistance?

• A. strength and resistance format
• B. HIIT and interval format
• C. boot camp
• D. mind-body

Answer: (A)

Using an opposing force to build muscular strength and endurance means challenging muscles with external resistance they must overcome. The strength and resistance format centers on applying resistance—via free weights, machines, resistance bands, or even bodyweight against a force—to make muscles contract harder and longer. This approach promotes gains in both strength and muscular endurance as overload is increased over time through greater weight, more repetitions, or longer sets. Other formats focus more on cardio and interval work (HIIT) or blend activities without the primary emphasis on resisting force, and mind-body focuses on flexibility, balance, and mindful movement. So the method that best targets increasing strength and endurance through opposing resistance is the strength and resistance format.
