If you have a pair of dumbbells you can build muscles like a pro. Just follow this workout 3-4 times a week and the results will be visible from after a few weeks.
There are 2 sets of 10 exercises each. Every exercise should be performed for 1 minute.
If you’re not tired enough after all the exercises are done, then you can repeat the entire workout one more time (or as many times you need). Have fun!
