The 10 Best Cannonball Grips

You're unlikely to ever push the Iron Bull Strength Cannonballs (appx. $50) fully to their limit, as they can handle thousands of pounds, whether you're swinging from or pulling on them. Plus, they come with a 100 percent satisfaction guarantee for extra peace of mind.

These Body-Solid BSTCB (appx. $45) can support up to 250 pounds, yet weigh in themselves at only 2.7 pounds, so they aren't much trouble to slip into your gym bag. They also fasten easily with a hook-and-loop-style closure, and feature welded steel hanging hooks.

You can pop the Gunsmith Fitness Grenadiers (about $21) onto just about any bar to instantly engage finer muscle control during lifting, which can maximize your effort with a minimum of hassles. They even come with a handy camouflage carrying case.

The Warrior Life Set of 2 (appx. $29) doesn't have any straps, but their anchors aren't all that difficult to use, so you may not even need any. In fact, they're compatible with cable weight machines and load tested to over 1,000 pounds.

Crafted from ash wood, the Escape Climbing Power Ball Pack (about $21) is a handcrafted option that is simple, yet effective. And because the hardware used in each pair is industrial grade, you can count on using them for a long time to come.

If you're truly serious about training, then you might check out the Warrior Life Gear Pro Ninja Kit (around $99). It comes with four pairs of grips, including candlesticks and bungee ninja squids, which will help you work out in new and productive ways.

The FITactic Training Bombs (appx. $26) are offered in two diameters, 3 and 4 inch, so if your mitts are bigger than average, you won't need to settle for an uncomfortable experience. They're also available in both red and black, in case you have a preference.

For those who are tired of slippery spheres, the Ya-tube Hand Exercisers (appx. $25) could be useful, since they've got a textured anti-skid design that lets you hold on with less trouble. And because they are bright yellow, they're always easy to spot.

Go ahead and grab the FitBar Ball Grips (about $39) any way you'd like, as they're comfortable whether you choose an overhand, underhand, or side hold. They're a snap to use, too, with uncomplicated J hooks that won't slow you down or require a degree in physics to figure out.

The sturdy, oversized carabiner that holds the CFF Pit Bull (appx. $30) can take the abuse that you throw at it, as it's made from hardened steel that's designed for the long haul. The strap is just as durable, rated for a capacity of 1,000 pounds.
