It really doesn’t take a ton of equipment to get in shape. You can use your body weight in a variety of exercises and get some good results. However, a few key pieces can really help. Like this Gold’s Gym 25cm Anti-Burst Core Ball. You can grab one for just $5.49! (regularly $11.99) This ball can help you tone your abs, back and thighs for half of what a monthly gym membership can cost. Be sure to select free in-store pickup to avoid shipping fees. Otherwise orders of $35 or more will ship free.
