With only 20-minutes of workout time to spare, I highly suggest clicking on HIIT YouTube workouts.
You can train at max energy and burn more calories in less time — plus, it takes minimal effort to access a free trainer for guidance.
Another bonus? The interval technique has a higher afterburn effect, which means you burn calories even after the session is done.
Yes, the combination of free training, shorter workouts, and burning calories long after you’re finished sounds like a breeze — but it’ll only take a few seconds for the following HIIT YouTube workouts to test your endurance.
