Straps: Straps are fastened around your wrists and then
twisted around a bar to strengthen your grip in exercises where
grip is your weakest link. Hand strength will not develop as
quickly if you use straps, but this may be worth the value of being
able to lift heavier weights which will result in a better
developed back. Weighing the opportunity cost of straps is largely
personal preference, and you can achieve great results with or
without including them in your regiment of bodybuilding aids.
