Does bullworker strengthen the heart?

A doctor has provided 1 answer

Device used for: Isometric exercise. Spring loaded, contracted cylinders are link to hand grips, and users push inward in both end of the device to work the arm muscle. Can be use for legs too. Isometric exercise contract muscle while stationary. At the gym we use mostly isotonic exercise for strength training. The best way to strength the heart is by aerobic exercise for endurance. Isometric wont work as good.
