The weekend can be a time when calories are high and time training is low. After a long week, the last thing some people may want to think about is going to the gym. Fortunately, you can still work on that physique sufficiently without spending a lot of time in the weight room with this 15-minute dumbbell HIIT workout.

US Army Veteran, celebrity trainer, and M&F fitness expert Erik Bartell knows a lot about making the most of workout situations. If you follow M&F on Instagram, then you know that he performs workouts twice a week live helping followers kickstart their day in a fit fashion. He doesn’t need much time and equipment to get the job done, either.

For example, he recently shared a 15-minute workout that will help anyone needing to burn some calories while getting an upper body pump. Yes, this session requires only 15 minutes of movement. Counting the time transitioning from one movement to the next, you’ll be done in around 20 minutes.
