Sold in Pairs. Frog Blocks are designed specifically for group classes to immobilize The Frog in a gym/studio setting. These wheel chocks allow an individual to isolate certain muscle groups such as upper or lower body.
The initial purpose of Frog Blocks were to give the end-user the ability to really train hard without worrying about The Frog moving from the initial position. With one set of wheels locked you are able to easily manipulate your workout by concentrating on Superman’s (Upper Body), Leapers (Lower Body), CoreKillers (Core) or Mojo’s (Knees to Elbows). The Frog Blocks just give an extra layer of insurance to the Lock position on the Hubs. Highly recommend this product to anyone that purchases The Frog.
