Conclusion: Which is Better?

Ultimately, the choice between a 45-minute full body workout and a 15-minute HIIT session depends on your personal fitness goals and schedule. If you're looking for comprehensive strength training and muscle endurance, the full body workout is your best bet. However, if you're pressed for time and want an efficient calorie burn, HIIT can be incredibly effective.

Next Steps and Progression Path

• For Full Body Workouts: Gradually increase weights or add more sets as you progress. Aim to do this workout 3 times a week with rest days in between.
• For HIIT Workouts: Increase the duration of each exercise by 10 seconds or decrease rest time as you get fitter. Aim for 2-3 times a week.

Both workouts can be tailored to your needs, and with the right guidance, you can achieve your fitness goals efficiently.
