Walmart offers the Gold's Gym Silicone Fitness Ring 2-Pack for $9.98. Opt for in-store pickup to dodge the $5.99 shipping fee and cut the price to $4.83. That's $5 under the lowest price we could find for a similar 2-pack. They have a lightweight design, are made of soft silicone material, and are suitable for any workout.

Update: The price has dropped to $3.99.
