These work not only your chest and triceps but also your shoulders, deltoids, and lats. This helps develop your core also by maintaining your balance as you do the lateral raises. You want to do a push up then a lateral raise with both arms and repeat for a set of 10 reps. if a dumbbell is too heavy you can use just your arms or any weight of your choice. Don’t swing your arms and keep a steady controlled motion throughout the movement.
