Title: Nice forearm exerciser
Review: Forearm strength trainer is great for portability and diversity. Able to do both wrist curls and wrist extension exercises. Just wish it had a tougher tension. Has great adjustability but if you are an avid weightlifter with pretty good strength then this may not have enough tension even on its strongest setting.
