Ab Crunch on the Powertec Multi System
Ab exercises are the source of a great deal of misinformation in the weight training world. Companies exploit people’s insecurities surrounding their guts by bringing out a wide variety of useless garbage that will give you a six pack in a week and a half. If you don’t know what I am talking about stay up and watch late night tv. In this video Brad not only explains how to do ab crunches properly on the Powertec Multi System but more importantly explains the important factors in an ab workout.
Customers often remark that there is not a lot of room for weight on the ab crunch on the Powertec Multi System. There is a good reason for this - you don’t need a lot of weight to do this exercise properly. You can move a lot of weight on this exercise but you will not be using your abs. You won’t get any benefit from turning a good ab exercise into a poor back exercise by using too much weight.
You can see in the video Brad is not using much but once you get yourself in the correct range and you load up the abs you will start shaking like a leaf in a strong breeze. The range of motion is just short and if you stay withing that range you will be keeping constant tension on the abs.
