DAREBEE Workout: What it Works
Deltoids and triceps help define the shape of shoulder musculature. The Arms Lift workout helps shape your anterior deltoid muscle and strengthen your triceps. It adds to the overall upper body strength and control you develop while helping you feel that your upper body is getting as strong as your lower body. Add EC and you incrementally increase the load the muscles experience. 
Extra Credit: Hold the dip position throughout the circuit, don't drop down.
