Killer Back and Biceps Workout
Bodyweight Mastery Program High Intensity Interval Training, or HIIT, has been shown to be the most effective and efficient means of achieving good cardio.

You can still do whatever exercises you want, split your workouts, etc. The beauty of Y44 is you only have to do one set of the exercise to get excellent results. In fact, doing more is overtraining.
