  • If you decide to use what is called an EZ Bar, you will not want to use a close grip, instead of keeping it approximately at your shoulder width area.  Using this type of bar can provide a person with ease in the wrist area.  Since you are gripping it at the shoulder area, it also makes for smoother balancing and less of the unwanted shoulder flare. 
  • When you decide to use dumbbells, each of your arms will move independently of the other.  There will be a short change in the amount of weight you can hold because the dumbbells are not as easy to control; this can be good or bad. 
  • Should you decide to use a long bench instead of the flat bench you don’t want the incline to be too high, this type of bench will give you more target on the long head.
