Conclusion and Next Steps

If you're pressed for time and need a quick calorie burn, HIIT is your best option. However, if you have a bit more time to dedicate and are focused on muscle gain and strength, consider the 30-minute strength training session.

To progress, alternate between the two workouts throughout the week. For example, try 3 HIIT sessions and 2 strength training sessions weekly, with rest days in between.
