Add more weight to your selectorized Athena™ and challenge your potential with the weight stack upgrade. The Athena™ selectorized side-mount functional trainer comes with a 170lb weight stack per unit, but we know that’s not enough for some people. That’s why there’s the option to upgrade the stack. This weight stack adds 50lbs to the weight stack, making the new total weight 220lbs (feels like 110lbs).  

The weight stack upgrade plates are made from durable, hot-rolled steel. You can choose this upgrade for just one single side or for both sides of the Athena™. The Athena™ features a 2:1 ratio, meaning 20lbs feels like 10lbs – ideal for functional and explosive exercises. The plates have a 3% tolerance.
