10. Push-up/Plank Workout
If you're looking for a workout to give you a brutal workout (for the best) then you've found it.
This works your upper body and core with nothing more than your body weight.
You don't want to neglect your beautiful body.
Treat it the way it deserves by exercising whenever you get the chance, even if it's only for two minutes.
When was the last time that you actually worked out?
