High-Intensity Interval Training (HIIT) involves short bursts of intense exercise followed by brief recovery periods. This method is effective for burning calories quickly and can be done without equipment, making it suitable for small spaces.

What is Strength Training?

Strength training focuses on building muscle through resistance exercises. It typically requires more time to perform effectively, allowing for proper form and muscle engagement.
