Power Block Sport Exp

This is a discontinued version. The expandable model PBSPSET2 starts at 22.7 kg (5-50) and then allows you to expand with a 9 kg (20 lb) set. The Stage 2 set increases the weight from 22.7 kg (50 pounds) to 31.7 kg (70 pounds), while a Stage 3 set increases the weight from 31.7 kg (70 pounds) to 40.8 kg (90 pounds). This is a great option for anyone who wants their set to grow with them.
