Depending on which option you choose, the Athena can transform your existing power rack into a functional trainer for as little as $500. We think the Athena plate-loaded unit is priced well and is a great option if you already have Olympic plates to load the unit. If you do not, you can take a look at the Athena Selectorized Side-Mount Functional Trainer, which is about twice the cost but comes with plate stacks.
