Quick workout routines that can be done with minimal equipment include bodyweight exercises like push-ups, squats, and lunges, effective for building strength and endurance. High-Intensity Interval Training (HIIT) is another option, combining short bursts of intense exercise with brief recovery periods. Routines utilizing a resistance band or a simple dumbbell can also be effective for strength training. The versatility of these workouts enables individuals to perform them anywhere, making it feasible to stay active while balancing a busy lifestyle.
