What characterizes interval training?

• A. Short bouts of high-intensity work followed by short rest or low-intensity work.
• B. Long, continuous activity with no rest.
• C. Only resistance training with isolated movements.
• D. Low-intensity activity performed for extended periods.

Answer: (A)

Interval training means alternating periods of high-intensity effort with recovery periods. The defining feature is short bursts of hard work followed by rest or lower-intensity activity, which lets you push hard, then recover enough to repeat. This approach contrasts with steady-state cardio, where you keep a consistent pace with no built-in recovery, and with purely resistance training that focuses on isolated movements or with long durations of low-intensity activity. Interval training efficiently challenges both the aerobic and anaerobic systems, and you can tailor the work and rest intervals to fit fitness goals.
