Strengthen and build definition in your arms in this 30 minute cardio and arm HIIT workout.
A little tip, the more muscle you have, the more calories you burn, even just sitting around.
Another reason to do strength training. These types of workouts are designed for creating and maintaining definition, not bulking up, as they go for higher reps instead of lifting heavy.
45 seconds of work with weights, followed by a cardio move to optimise the fat burn.
