Time may not always be on your side to train, but you don’t need to push yourself to the point of exhaustion in order to get results anyway. This 20-minute workout is perfect for those days you need to be in and out the gym, sharpish. It’ll target all your major muscle groups from head to toe, whilst accelerating fat burn too. All you need is a pair of dumbbells or a kettlebell.
The bulk of this workout is made up of supersets, but there’s also a tri-set thrown in at the end for good measure to really raise your heart rate. The main benefit of these training protocols is that they help reduce your workout time. However, they still allow you to train hard as research shows— despite the study being pretty small— that they can be just as effective as traditional training sets when it comes to building muscle.
