Seen as your triceps make up two-thirds of your arm, if your goal is to get bigger guns then you need to give them some attention. This quick-fire tricep session simply requires a pair of dumbbells and is ideal for either doing as a standalone workout during those days you don't have time for a full-blown gym sesh, or adding onto the end of a chest or shoulder workout.
As time is of the essence, this workout takes the formation of a circuit. Circuit training is great for those days when you need to smash through a series of exercises in a short space of time. Studies have shown that resistance circuit training can help build muscle lean muscle, due to the ongoing tension your muscles are under, as well as burn fat. However, the short rest periods will also cause your heart rate to rise, so you've got a bit of a cardio workout in there too, which is ideal if you've been sat at a desk all day.
