Why 45-Minute Full Body Workouts Are Overrated: The Truth Behind Shorter Sessions

For busy professionals, finding time to fit in a long workout can feel impossible. The idea of committing to a 45-minute full body workout often leads to gym intimidation or burnout. Many people believe longer sessions equate to better results, but that’s not necessarily true. Shorter, more efficient workouts can be just as effective—and sometimes even more so—especially when you're short on time.
