How to Set Up C840 ProForm

The ProForm C840 is an exercise system that includes a locking barbell, a weight bench, a lat tower and a curl bar. The barbell runs along a track that has locking holes and stoppers to protect you from dropping or losing control of the bar. The C840 takes standard, one-inch weight plates, but the system comes with adapters so you can use Olympic, two-inch plates. You will have to adjust the settings on the bench and rack before doing each exercise.¬
