The Total Core T-Bar Toorx AHF-198 is a portable rotational base for barbell training. One end inserts into the hole of one or more Olympic weight plates to create a stable support point. The heavier the stack of plates, the more secure the support will be without slipping or tipping over, especially when performing dynamic or rotational movements. On the other end, you place an Olympic barbell and on the free end, you add plates according to the resistance you want for the exercise you will perform.
