15-Minute Belly Fat Workout for Those Who Are Too Busy to Go to the Gym

I do the same twists, but also hold dumbbells i my hands for some extra pressure of he belly area ?

Oh, this is the easiest set I have found yet! I wanna try them all ?

I think stairs are prefect because you have them literally anywhere: streets, offices, apartments, etc.
Not many people like them and prefer elevators instead, but they are actually useful to make a fast workout :p

Good ones, and pretty simple. Will try :)

Twists are cool for guys too ?
